Failure to pay out loan and refusing to

I app**** for a loan and they told me that I needed to pay only one upfront fee. I paid that then I was requested to pay CTO and service fee =R1600 I did that,then I was told that my funds will be in my account within minutes. After an hour I was told I needed to pay for Stamp of duty another R1600 - which I did....still no funds. I was later told I needed to pay an additional R1300 since I paid the money late I did just that.... Still no funds. I was told I needed to pay an equest fee - I did that, I was told it was paid late and needed to pay an additional R1583 - I did that. I then received a text that everything was done and dusted and that I will receive my funds. The following morning I was told to pay a service fee of R1500 - I refused and told them to pay me back my money. They told me cancelling was not a good idea. Till today I have sent them emails requesting my money and a cancellation form and they do not respond to my emails.
