I've had the same thing happen. After a couple of attempts to contact the original buyer (with no success), I sold it to the next person in line ( who paid for it immediately ), then sent the original party a message that the ball had been sold to someone else due to the fact that they had not sent the payment and could not be reached.
They weren't happy about it, but I wasn't trying to make anyone happy, I was trying to sell a ball.
If you buy a ball from me, you will be made happy SOMEHOW. If you don't buy, won't pay, and can't be reached, it isn't my problem anymore. I'll give you a chance (or two), but I won't wait forever. I missed a sale once like this, but I won't miss another one.
If he ends up sending the payment afer you've sold it elsewhere, it can easily be refunded.
