Frustrating, non-service from WesBank vehicle finance.

If I could actually give a minus star I would! I reached the end of my vehicle finance term with WesBank recently. There was a small amount to be debited from my account as the last instalment. My regular instalment was around R2800 but the remaining last instalment was R359.00. One month went by, a second went by and I noticed that WesBank were not collecting the last instalment. I called a few times and was told that they were unable to as "their system didnt allow any deviation from the regular instalment". Now I know that this is nonsense. Remember too, that interest was being added to this small amount. I instructed WesBank to give me an immediate settlement figure and to debit my account the following day. A debit of R460.89 was passed, thereby settling my account. Today I received my electronic statement from WesBank saying I owe a further R59.15. Now this is not a lot but every time I settle, I get a further small amount owing. I called WesBank today, and was immediately put through to the Collections department because the system indicates that there is an outstanding amount of R59.15! When I explained the situation to Steven Matsimela, I was told rudely that I was wrong. There was no outstanding amount on the account according to him - even though I had been put through to collections immediately. So I called the NATIS department of WesBank to get my registration papers - only to be told that there is an amount of R59.15 outstanding. So I call Steven again, same story. In a condescending manner, he telss me that my account is settled and I must "be imagining" my statement in front of me. So, I cannot get my car papers, nobody calls back, but I know that if I do not pay this R59.15, more interest will be added. Disgusting company!
