I found reviews and complaints for all three companies. Sunrise Computer generally has good reviews, although a related service (Sunrise PC Support) was accused of deceptive practices. Repair Center appears to be a generic name, with no clear complaints but mixed reviews across different repair shops. Karls Technology Computer Service does have several complaints on consumer sites, though it also has positive reviews elsewhere.

🌅 Sunrise Computer

• Trustpilot and Trustburn show positive reviews, with ratings of 4.1–4.4 stars, highlighting good service and customer care.
• Sunrise PC Support (a related service) received complaints on ComplaintsBoard for trying to charge $299 for a supposed “virus” that didn’t exist. The case was resolved, but it reflects accusations of deceptive practices.
• Sunrise Computer Repairs (Fort Lauderdale, FL) has 29 reviews with a perfect 5.0 rating, with customers praising fast service and successful data recovery.

👉 In summary: the “Sunrise” brand has a good reputation in local repairs, but a related service (Sunrise PC Support) was accused of a scam.

🛠️ Repair Center

• The name “Repair Center” is very generic, and multiple businesses use it.
• On Yellow Pages and Angi, repair centers in Plantation, FL, show generally positive reviews (4.6–4.8 average).
• On forums like Reddit about Microcenter (a large retailer with repair services), some users report negative experiences: incorrect diagnoses, delays, and issues after repairs.
• Other services like Computer Repair Doctor have mixed reviews: some satisfied customers, others complaining about delays and minor issues.

👉 In summary: there isn’t a single company called “Repair Center” with specific complaints, but common issues in the repair industry include misdiagnoses and long wait times.

💻 Karls Technology Computer Service

• On ComplaintsBoard, Karls Technology has 1.2 rating with 18 reviews and 5 complaints, including accusations of unprofessional practices and dissatisfied customers.
• On Birdeye, it shows 3.9 stars across 89 reviews, reflecting more balanced experiences.
• On RevDex, reviews are mixed: some customers highlight honest and fast service, while others complain about cancellation policies and lack of clarity.
• On Indeed, employees report internal management problems and questionable practices.
• Another complaint on ComplaintsBoard describes poor service in SSD replacement.

👉 In summary: Karls Technology has multiple documented complaints on consumer sites, though it also has satisfied customers in local reviews.

📌 Conclusion:

• Sunrise Computer → good reputation in local repairs, but beware of Sunrise PC Support (accused of scam).
• Repair Center → generic name, mixed reviews, no clear complaints but common industry issues.
• Karls Technology → multiple complaints documented, though balanced by some positive reviews.

Letter to Mr. Matthew Karl

Davie, November 18, 2025

Karls Technology Computer Service (and affiliated entities: “Repair Center” and “Sunrise Computer”)

Attention: Matthew Karls, Owner Email: support@karls.com / billing@karls.com

Yesterday I received a visit from one of your technicians to resolve an issue with my computer: there were files that I was unable to delete. When I initially contacted your company—through what I now understand to be the affiliated entity "Repair Center"—to schedule the service, I clearly and explicitly informed you of the exact nature of the problem and clearly warned that the technician you sent must know how to resolve it and should not spend an excessive amount of time figuring out how to do so.

Your company assured me that the technician assigned to my case was highly experienced with Microsoft systems and that he would not take longer than necessary to delete files that could not be removed through normal procedures.

When the technician arrived and I explained the issue, he first told me that the las time he has a similar issue was three years ago but later told me that he had never seen anything like it but that he would try to fix it.  After almost half an hour attempting to understand the problem, he suggested changing the entire operating system on my computer, which would have caused me to lose functionality, applications, and programs. I replied that this was not an acceptable solution and suggested he return to your office, properly consult with someone, and come back once he knew how to resolve the specific issue.

He then informed me that he would call several people for guidance, which took almost another half hour. In other words: after NEAR ONE FULL HOUR (not the hour and a half indicated on your invoice No. 5513079) and after consulting multiple colleagues, the technician partially resolved the problem using a procedure that would have taken not more than 40 seconds had he known what he was doing from the beginning. I have attached a video showing how he partially resolved the issue.

I emphasize partially because, even after applying the procedure your technician learned on the spot, there are still files that cannot be deleted. If you send a competent technician, he or she will immediately confirm that the problem persists despite the method your technician learned while at my home—the very service for which you are now charging me the outrageous amount of $254.00 under the unfamiliar name "Karls Technology," an entity I had never heard of prior to receiving the invoice, since I called “Repair Center” – Phone 754.241.1655.

Had your technician known how to delete the files in question from the start, the entire job would have taken less than one minute. From now on, whenever this same technician encounters a similar issue, he will at least know how to start with the procedure he learned while he was at my house, at my expense.  Incidentally, after contacting other technicians who were recommended to me later, it turns out that the issue addressed by your technician is extremely common, if the person dealing with it is a true professional in the field.

When I asked how we would adjust the billing to reflect the actual service provided, the technician became angry, left abruptly, and behaved in an unprofessional and disrespectful manner.

Furthermore, in an effort to resolve this matter amicably, I contacted your dispatcher today (November 18, 2025) via the phone number associated with "Repair Center" to request a physical address for sending formal correspondence, such as this demand letter. I was informed that your operations—spanning "Karls Technology," "Repair Center," and "Sunrise Computer," all reportedly owned by Matthew Karls—do not maintain a physical address and can only be contacted via email. This refusal raises serious suspicion regarding the legitimacy of your business practices. Under Florida law, specifically Section 605.0113 of the Florida Statutes (Florida Revised Limited Liability Company Act), any limited liability company or other business entity operating in the state must designate a registered agent who maintains a physical street address in Florida (not a P.O. Box, private mailbox, or virtual address) that is accessible during regular business hours for the receipt of legal documents and service of process. A thorough search of the Florida Division of Corporations' official database (Sunbiz.org) yields no active registrations for "Karls Technology," "Repair Center," or "Sunrise Computer." The only related entity found, "Matthew Karl Boltz LLC," has been inactive since 2011 and lists an address over four hours north of my location in Davie, which bears no relation to your South Florida operations. This apparent lack of registration and unwillingness to provide a required physical address suggests unauthorized business activities, further supporting my intent to pursue regulatory complaints.

I demand that within ten (10) calendar days of receipt of this letter you:

1. Issue a corrected invoice for a reasonable amount that reflects the actual time and skill required (no more than $50, given that a competent technician would have resolved the issue in under one minute).
2. Confirm in writing that the remaining undeleted files will be removed at no additional cost by a properly qualified technician, and provide the physical address of your registered agent as required by Florida law for any future correspondence.

If I do not receive a satisfactory written response and resolution by November 28, 2025, I will have no choice but to file a formal complaint with the Florida Attorney General’s Office under the Florida Deceptive and Unfair Trade Practices Act (FDUTPA), file a complaint with the Florida Department of Agriculture and Consumer Services, and pursue my claim in Small Claims Court for the full amount plus court costs and any applicable statutory damages. I will also seek recovery of my filing fees and any additional remedies available under Florida law, including penalties for operating without proper registration.

Sincerely,

Roberto Alonso
