User hasn't paid

[fapat5]

I didn't know where (or even if) to post this, but it has been annoying me a little, and as such this morning I thought I'd just do it.

A guy purchased a Dovo Bismarck from me from the classifieds section here on SRP. However, instead of paying me in British Pounds (which I asked for) he paid me in US Dollars. Obviously this means that he paid me less than he should have. I rejected the payment in PayPal (they need authorisation for incoming payments in different currencies so they can slap their conversion fees on top) and sent the guy an e-mail, letting him know of the problem.

While I would have been annoyed if he'd written back saying he didn't want it anymore (due to the price) I would have nevertheless moved on. However, I have not heard back from him at all. Nothing. In fact, I cannot even find any posts or anything else by him on this website.

Does anyone actually have any contact with this guy at all, in case he merely hasn't checked his email inbox (though it seems unlikely)?
