Having problems with my iMac G5. Upon 7 months of purchase, I experience my 1st Mac breakdown and needed to reset my PMU although it was a suspected logic board failure. 3 weeks later, my logic board did break down. Yo compound matters, the AppleCare that I purchased was not found in the database although the Singapore's Office did confirm my registration. Hence, no assistance was rendered. May I know where I can complaint about the poor product quality and terrible service? The Mac website is really terrible on this aspect. This is my 1st Mac and after this bad experience, tyhis will definitely be my last Mac too.
