NPS online-pharmacy https://canadadrugs365mm.com/contact/ They stated the charg would be 4431.95 but charged my credit card $486.68 and even after presenting the CC statement now they say they didn't do it unknow aka India Internet

On 9.14.16 I purchased my selected product under order ID:16816-547 and Tracking# ED908824524IN. That same day I emailed the company and stated, "you charged my credit card company $486.63 instead of $431.95 as agreed upon", after many emails, this frudulate company says they are going to refund only the $431.95 instead of the full anount, After many other emails they are no longer answering my emails, My credit card company said there wasn't anything they could do. So basically this company says it's going to refund some of the monies yet nothing has been refunded plus I'll be out the additional $54.68. This company is a total fraud
