I had a similar experience selling a Samsung Galaxy phone to Morocco a year or 2 ago. I thought that the entire continent of Africa was on my exclusion list, but he had found it and paid for it anyway.
That was when I discovered that "international flat rate" postage was only flat rate to the civilized world, and the charge was more than half again the going rate to Morocco.
I sent it out promptly, anyway, knowing that the Post Office international tracking, at best, stops at the border of the other country.
Within 2 hours of the Post Office tracking post noting that the package had left Miami, the buyer posted a "item not received" complaint (this was no more than 2-3 days after the ebay sale) with Paypal. When I sent Paypal the tracking number, they accepted my word.
When that happened, the buyer started in with the "somebody hacked my account and bought the phone without my knowledge" routine.
Paypal held my money for a few more days, but after a couple of more messages from me (with plenty of solid sales and 100% positive feedback) they released my money.
