Wesbank poor service, they fails to disclose what I am been charged for

Two months ago I requested Wesbank to do apply capital reduction to my vehicle finance deal. The vehicle finance deal commenced in June/July 2025. On the deal was loaded a warranty which I quickly cancelled with Innovation/Gatewayassist group who repaid the R15K warranty back to Wesbank. However, when I asked for the capital reduction, lo and behold I am charged and debited for a warranty and some other amounts. There are now all of a sudden two debit order where I only had one. I asked Wesbank for the supporting documents for the charges of R466 (warranty) and R602 (which I have no idea). Wesbank Mr C Saad not able and guess willing to assist and said I must speak to the suppliers. This is really poor customer service from Wesbank.
