Ebay gomper

We sold a couple of things on Ebay recently. One of the items went smoothly, the other - not so much.
When the auction ended I sent an invoice to the buyer - no response, no payment.
After a couple of days I sent them a reminder email via Ebay - no response, no payment.
After a couple more days I did the same again - no joy.

Today, I sent a snotty text to the buyer, telling them if they didn't contact me within 24 hours I'd have to report them to Ebay.
Finally I got a call from the guy, who is a complete TIT. He was bidding from his iphone, using his wife's account. It didn't occur to either him or his wife to actually log into Ebay and check to see if they'd won the item. Duuuurrrrr.
What a gomper.

So he says he's going to pay us tomorrow. I'll believe it when I see it.
I won't be in too much of a hurry to post the thing.
