A bit of an update:
I returned iMac number 3 today for a refund. They tried to convince me to have the current one repaired (it's only 7 days old!) and then suggested I try another one (because I love driving 2 hours each way!). I was then told that having 3 defective units in a row was highly unlikely (even though they acknowledged the yellow tinge problem) which made me feel like they thought I was lying about the whole thing.
Over the last 2 weeks I have been promised twice that a manager will get in contact with me, which hasn't happened. Again today I asked to speak to one in store, and again I was told they are all in a "meeting" and I will get a call back. I've written emails to the store (which I was told was the best way to get in contact with a manager), and haven't received a response, and out of desperation I even wrote one off to
sjobs@apple.com. This is seriously frustrating.
I know I can't be reimbursed for all the time and money I have wasted, but this is probably the worst customer service I have ever received, and I would at least like someone to take responsibility and say this should not be happening. Does anyone have any ideas about what I can do from here? Anyone else that I can contact (I'm in Australia btw).
