Cars papers

I am very disappointed in the service I have received from Wesbank. I paid my car off on the 28 September 2017 and I was told my papers would be delivered to me. Knowing that I have 21 days to then put the car in my name. I have phoned them 5 times now to query what is happening as I still have not received my papers. Every time I phone they tell me that it is set for me to collect and every time I say that I need it to be couriered. Always giving them my information for delivery and I am still waiting! Tuesday I asked to speak to a manager and it is now 3pm Thursday and I have still not received my papers!
