Very poor service from Nedbank

I purchased a car from through Nedbank finance in 2007. I settled the amount owing in 2008. They did not send me the license for the car. 16 years later i was told at the licensing department that Nedbank has the original paper and that I should contact them to issue it to me. I contacted mfc and I was told that it will take 5 to 7 days to send it to me to their branch. I contacted the call centre on four occasions and emailed them on about four occasions, explaining that I need the papers urgently to sell the car for the new owner to register and insure the car. all i received is the same standard reply that they are working on it but nothing is being done. The consultants shove you off saying that there is nothing that they can do. They won't give me a number for the archive department. I was told that a consultant will call me. I want my papers, not another call. I am so glad that I don't bank with Nedbank. I have never received such shoddy service. I certainly will never consider buying any if their products after this bad experience
