So, I had an auction end about a week ago and the winner has had no contact. I've invoiced him and sent a couple messages...nothing. He also won the auction at the last minute which to me would mean a quick payment since he's already bidding live and should know that he won. I usually have no problems getting prompt payment so this is annoying as hell. I really wanna just sell to the next highest bidder. Anyone know how long I need to wait on this ********* before I can just negate his bid?
