I brought my 4 year old Apple to Best Buy Geek Squad due to sporadic shut downs. After reading information on the internet about similar problems, I informed the Geek Squad that I suspected a bad power supply. They informed me that they charged a $70 diagnostics fee. They also informed me that there would be a $100 charge to add 2 gigs of RAM about which I inquired. After three days, I got a call stating that the problem was in the Operating System and that a $130 services was needed to fix the problem. The 2 gigs of RAM were now going to cost $170, not the $100 originally quoted. Service to fix the problem was OK's, but addition of the RAM was not. I had just updated the OS several months before, and never had a problem, but they are the experts, right? Several more days passed, calls were exchanged, and I was able to pick up the computer. After bringing it home, it shut off just as before. They said it was still under warranty for the services performed, and to return it. After several more days, I received a phone call stating that the problem was the power supply after all, a suspicion I reported when I brought there in the first place. I was informed by the Technician that the power supply was a "proprietary" item, to which they did not have access. "If you can bring us the part, we can put it in." Promises of obtaining the part number and returning phone calls were not kept. I was informed by the Technician that my service charge (prepaid prior to work performed) would be refunded. I informed them that I would pick up my computer and wanted a full refund, including the diagnostics charge because they withheld information about not being able to fix a suspected problem in the first place. The supervisor stated that it is not their policy to refund and that all services were OK'd by me. They offered to find and install the part, which previously was unavailable. By this time, Geek Squad had proven themselves to be non-trustworthy and inept, so further service was declined. The Geek Squad wasted 2 weeks of my time, performed unnecessary work, delayed repair of my computer, and they refused to refund any of my $212. I filed a complaint with their central public relations division, but they reported they could do nothing about securing a refund. They seemed genuinely disinterested that their employees provided misinformation, low-balled estimates, performed unnecessary services, failed to follow through on promises, and showed a pattern of general deception. Resolution will continue to be pursued.
