Had the same with my work MBP. Started about 6 weeks into using it, went to the Apple Store and got told it would take at least 14 days. Asked them for an exchange device so I could keep working and they almost laughed at me.

I bought mine on an American Express credit card which, in the UK, has what's known as "Section 75" protection. This alone means I can return it for a full refund since it is a defective product within the warranty period with documented design flaws. If Apple refuse to issue the refund, then Amex will do it for them. Obviously it will need persistence and a bit of a fight - but the law is 100% on my side.
