Marathonkickzz, Payfast, Amarex stay away!

I recently bought shoes from Marathonkickzz.com a South African company. It was a complete nightmare from day 1 I've been battling with them since the 19th of November try get a refund on my purchase . But I've had no success. I've contacted every company that does business with them but still no help getting my money back. Payfast. Co.za was the company that did the payment I've sent over 20 emails to them but still no help getting my money back. They have been so arrogant and after this experience I don't think I will ever do another online purchase. Surely Payfast has to verify to company is legit and no a **** before they take money for goods ? Is it the wild west out there any one can **** you? Even a big company like Payfast. Co.za
