All i want is my full refund back and my car registered

<p>So I took delivery of my Kia Rio on the 26th April. Traded in my Ford Figo. I was debited by Wesbank on the 26th and immediately told the sales agent as he was pushing for me to sign the papers before the 15th to avoid this. He said it should be a problem the money will be refunded back to me. First it was suppose to be refunded on the 4th that changed to the 11th then it was the 18th. He them told me that there was some error that transunion did but I will get the refund on the 19th I get an sms saying R2111 is deposited into my account. This is less than what the debited instalment is. I call the sales agent he tells me that there are some charges and so forth and that his manager will call me back. Till now the manager has not called. Why was I not told about all this when I bought the car and why was I told to sign the papers before the 15th if I was still going to experience all this trauma? Icing on the cake a cheque is deposited which will take another 14 days to clear. All I want really is my money back. I don't want to be dealing with such. the manager doesn’t call me as Arise promised, i then has to call back.the sales agent gave me some weak story about wesbank charging interest because i took delivery late, why was i not told of all of these this? why did he say i will not be debited by any bank on the 26 April? which bank is going to debit me on the 27th May? this is unacceptable service oh and icing on the rotten cake i am still driving the car with a permit, will it ever be registered.</p> <p> </p>
