Wonga loans dishonest and something must be done about this I lost lot ofmoney and still no loan

Its like a week later and still nothing from Wonga they didnt phone me at all as they say on the reply I even send them my number a couple of times. Why is there companies that just rip ff people? *****ing from people because still no loan and I pay a lot of money that I lost because on there website it wss a registered company and NRC number so then you think it is legit. What can we do to get my money back that I already paid for nothing all they say I must pay more money in but how can I trust them I already pay in R17100 with nothing. All I requested is pay my money back and then there must be an investigation on that company. If they say people do ***** on their company then they must secure their things better and also the number I used is the one I received the messages also from so I dont think it is in any way other people but Wonga itself that do this because as I write a review they reply on my whatsups
