Frustrating and Unprofessional service from Wesbank

I approached wesbank when I wanted to purchase my second car and at that time I was given a quotation that included the settlement of my other car but that car was still in the process of being settled. When I asked Gustav Dormehl, he advised that I can go ahead and conclude the deal for the second car and when the first car is settled then I should just call the customer care for them to include the settled vehicle and my installment will be recalculated. I have been calling and waiting for consultants to call me back for about 3 months now to have my installment recalculated but no one in the customer care seems to know what I'm talking about and when I speak to Gustav Dormehl, he keeps telling me that he will connect me to an agent to help but that always just ends with me being sent from pillar to post when I reach the customer care. I have now even been unfortunately retrenched and I would really appreciate to be assisted urgently regarding this matter.
