Ebay idiot I need help

[SlowWhite]

Ok I just won a bid on an I/O camera mount for my cage. and so I paid it, I then logged off and checked some other sites when I came back to ebay it said I needed to pay for it still. (thinking it didn't take) I resent the money, now on my account overview it shows that I paid for it twice.

Now what the hell do I do? I emailed the seller telling him what's going on. But am I supposed to file something with ebay or what ever?
