Bad Service Experience

On the 21st of January I made an online purchase from the Snatcher website and paid using my credit card. I received my proof of payment and was confident that my purchase would be delivered soon. It has now been 10 days and I have received 2 emails from Snatcher that states that my payment is pending and that my order will be cancelled if I don't pay for the purchase. I have notified Snatcher twice and sent them my PoP, but I only receive the threat that they will cancel my order if I don't pay. This is absolutely shocking service and I don't think I will make any more purchases from the online site ever again.
