^ Same here. Only thing I can say is check spam folder (which you've likely already done) and just keep an eye out.

I see. Well then, I suppose I should shoot them an e-mail, cuz something went wrong. Money certainly changed hands, but it didn't register for some reason.

Glad you got it figured out.. :)
