Ok, maybe better. Wait for the last day till you can use the buyer complaint thing on paypal. I still have 3 days. I mailed him today. I'll also call my bank tomorrow and see if it can still be cancelled. If so, I'll also wait for the last day, then cancel it. I don't think I can still cancel the credit card transaction though, :-( I think it's done at the end of the month...
But some of you might still do it.
I say wait till the last day. If you have no confirmation of your cards then cancel it.
