What do you mean a virtual bank account? Those are used for verification ONLY, not withdrawl. You need to find another way to cashout if that is what you have added to your account, because you can't withdraw money to a VBA.
A word to the wise, Paypal is cracking down on VBA's as of late. Best to finda nother way to attatch a bank account to your account if you are interested in making it last.
