Bad for business!!

This company is ****!!! I app**** for a loan and paid the R1180 then after that they required another R2500 I paid that too. After all these fees that was paid they requested another payment of R3700 to release my loan which is absolutely crazy. I requested a refund and was told I will only receive my refund after 7 working days and they received the payments I made immediately but refuse to pay me back my money immediately. DON'T APPLY GUYS THEY WILL WANT MORE MONEY FROM YOU THAN WHAT YOU APP**** FOR. THERE SERVICES ARE ****!!!!!!
