Same thing happened to me. After almost a month (which is ridiculous), 4 emails and a phone call (314-558-3097 went to VM, though), and no response at all...I called up my credit card company and filed it as a fraudulent charge. I explained the situation as well, telling them dates (date ordered, date I got the payment receipt, date the charge hit my credit card, and the dates of the emails I sent them) and description. My credit card company is putting a temporary reverse on the charge and opened up a case that is now under investigation.
Along with that, I filed a complaint through the Better Business Bureau to them the BBB to investigate as well.
File a complaint with the BBB:
I think this is the best way to handle it, since the company never responds...
