I had a problem like that the day the new store came out. I got a notice that there was a problem with my card when I submitted the order but then got e-mails saying my purchase went through. I sent a few e-mails the next day trying to straighten it out. I eventually called when I was at home and literally within 2 minutes of dialing they had resolved it for me and I've had no problems since. My lesson was to just call them if I wanted a very quick response.
