Wesbank charging R350 and not delivering

Wesbank is very poor in delivering Natis documents for cars that have been paid up. They also do not communicatewith there customers. I have paid R350 for this service which was promised would take 10 to 14 working days. It took them more than a month to do this. When I phoned the call centre they rep**** that they could only provide feedback after 14 days. Thats like following up on a querie with another query. I want my R350 refunded to me because I did not receive the service that I paid for.
