Do not sign up at Zimbali Vacation Club

I visited the resort and was called in my room to take a tour of Zimbali. I was asked to join the vacation club after the tour which was amazing by paying a deposit. I was told that if I don't cancel within 7 days I will forfeit the amount I paid, which was R4000. A few week later, I decided that I didn't want to continue with the membership and asked to cancel. I was told that I must pay 40% of the purchase price as admin fees to cancel which I was not told about and every time I ask where in the contract it specifies this no one responds. They only email me about a breach and not answer my questions. How can I trust a company like this which is clearly ran unprofessionally by ignoring me. I don't even know if this company is real or a **** to be honest with the way they are behaving. If you go to the resort and they call, don't go unless you know what you are getting yourself in.
