PAYFAST!!! ****!!! ****!!! ****!!! ****!!! PAYFAST!!!

Payfast is a ****... Please do not use their platform... They have taken my money and still asking for more money... I haven't received my money for two weeks... They keep sending the same email saying that they have accidentally taken out extra money from the buyers account and that since they can not reverse the transaction i must send them the excess amount so that they can send the full amount into my account... This has been going on and now.. They first asked for 4 800 and now its 17 000
