Unfair treatment

So last year 2017, I signed up for debt review and eventually those guys are ******, I decided to cancel and pay my car by myself. Until I realised that my car had accumulated interest which I worked very hard at reducing.

In December 2017 my arrears were R17000 and one of the consultants AT Wesbank debt review department called me regarding the arrears, she said because I had cancelled debt review, omeone from the legal department would call me regarding a payment arrangement. Someone did call me, and She proposed an arrangement to be made and I agreed that i would pay an additional R1500 to reduce my arrears. They are now sitting at R11000. I paid that every month including my normal installment, but wesbank kept on putting legal fees, informing me that my car will be repossessed, even though I am paying my car. I do not know what is going on there but this is seriously wrong and unprofessional. No one is answering my calls, the lady i made arrangements with is never available, the lady handling my account now does not want to talk to Me, she is always in a meeting, and never returns my calls! THIS IS MESSED UP!
