I have not done that (yet). The domain was actually sold, and the buyer did make a payment. It's just that he might not be using his credit card, and because of other circumstances (like changing credit card holder name during payment session), 2Checkout has marked this transaction as suspicious. He has agreed to follow up or even make a second payment, which up till this minute has not yet materialized. However, I don't want to void this sale by taking any drastic action now. Like I said, he does have some presence here and in a number of other forums; I just hope he treasure his reputation and resolve this complication promptly and amicably.
