Refund process horrible

I deposited R4000 into WBC account to participate in an Auction on the 26th June, and the bidding process went through. Following the conclusion of the car sale, I requested for a refund, all the necessary documentation has been provided on more than two occasions to process the refund, Till date Im still following up on this request with no update. This is very bad customer service, the delay and lack of response is frustrating. Its suddenly hard to get hold of the sales person now that the purchase has been concluded.
