It's sort of funny, but sort of annoying as well... Hardly abusing it, it's a genuine claim and don't tell me you would REALLY destroy your old unit, because of course you wouldn't. What you did with it however is a different matter...
I'd still like to know who did it, though. And why.
It's not so much the "you have to send it back" stuff, but the "I have to pay for it and we don't give a toss if you can't afford it".
