Apple case: 105025404 MINOR TO MAJOR PROBLEM!!!!!! Mac Specialist (service provider) was dispatched to go on site to replace a power supply that is making a noise. They arrived at my place 9/17/08 around 3:00 pm and they replaced power supply, motherboard and fan, after they replaced all the parts my computer does not power at all, no power (dead) . They said they received bad parts from Apple. I asked Mac specialist to put back my old parts so I can work and they said its impossible. Mac Specialist left my computer unusable. It was working before they came and the reasons for the onsite service were to avoid downtime. Ive called Mac specialist and requested to speak with a manager with no luck and no response. Now I have to take my computer to Apple store to get it repaired. According to the Apple rep, it will take 3 -5 days depending on the part availability . I do not want MAC SPECIALIST to work on my computer as they are an incompetent service provider. I am totally disappointed and feel mistreated. I strongly believe that MAC SPECIALIST did a mistake by leaving my computer down. They left the computer open and after looking inside the computer it looks to me that the P/S was never replaced because of all the dust in there.
