Karls Technology review: $900 later and still 2 broken computers!

EXTREMELY disappointed at the service we received and the customer support afterwards! We had an inexperienced technician come out for a repair job on 2 different computers. He proceeded to run some diagnostics on the first computer and then was Googling the problem trying to find things to do and reading through articles (I could have done that myself)! We asked him multiple times to consult with a more experienced technician from his company if he didn’t know how to fix the problem, but he never did. He admitted to us that he had only been with the company for 2 months. When he finally got to the point of wanting to “try” reinstalling Windows to see if that would fix the problem (he still wasn’t sure if it would), we told him we needed to verify all of our data was backed up to the cloud – which is a good thing we stopped him because we found out that we were missing some critical data; data that I’m sure he would have just erased.
On the second computer, we asked him to just briefly have a look since he was already there and charging us a trip fee to see if he knew what the issue might be and if he could fix it. Again, he seemed to have no clue on what was causing the issue or how to fix it. We told him multiple times to wrap it up and finish up as he had already been there for several hours, but he proceeded to keep trying new diagnostic tests. I finally told him I wanted to try the temporary work-around fix I had used in the past to get the computer back working after Windows updates and it at least got it back to a usable state – although we still have the original issue as nothing was actually fixed.
So almost $900 later and still 2 broken computers that were in no better shape than when the technician arrived, and we are just left stuck with an enormous bill! What a waste of time and money! The customer support afterwards has been hard to reach and slow to respond. They refuse to budge on payment as the technician documented his arrival and departure time and did some diagnostic services. They don’t care if they get your computer working or not, they just care about racking up a big bill so they can get paid! I would stay far, far away from this company!
