Yes I fumbled the ball, but I'd expect Apple to at least allow a little leeway considering they got nigh on 3 grand out of me for 1 usable computer!!!
Anyway thanks for your not necessarily helpful input.
I'm afraid my input isn't very helpful either but here goes:
I take it all of this occurred in the UK? I have found that the Apple UK staff, especially phone support, are utterly incapable of exercising any form of discretion or intelligence in their dealings with customers.
They, in effect, act as though any concessions they might give you will come out of their money and so like the worst caricature of a gypsy they try to do everything in their power to get out of having to do anything for free.
By contrast, the American Apple staff are amazing. They suggest solutions to problems that I would never have dreamed of expecting; for instance, my iPhone cable became frayed at one end, and it was a week out of warranty. I went to my local Apple store in London thinking that cool, "different" Apple would just give me a new one since it was only a week out of warranty but in effect they gave me the whole "computer says no" answer.
Disgruntled, but not disheartened, I went home, phoned Apple Care, spoke to a Texan, explained my situation and within 3 days I had a new USB cable.
So now if I have to call Apple Care for support, if I get a Brit I tell them I dialled the wrong number and keep trying until I get a yank. If you want a taste of that leeway which Apple is famous for I suggest you do the same.
