Don't worry about the strong language you directed to them. I too have used phrases in the sense of 'I demand....'.
Their english is not so good either. Perhaps with 'ending business' they just ment they would not send you another controller. They might have run out :lol:
Anyway I think it is no excuse for a one man internet shop since an 060 accelerator still costs over 200 euro. This may be cheap for a 060 card but it is still alot of money. If things go wrong you just can't treat customers like they do. It is just too much money for that.
'Pulling a Vesalia' I like it. But still; They solved the problem I had with them with style. They went wong, tried to solve it. But went wong again, but kept on trying and all was sorted in the end. I send them emails which were not responded by another email, but they were (eventually) responded by action. I would think twice however, before I'll go buying something expensive from them again.
