Wesbank's appalling service costing individual's unnecessary interest!

Utterly disappointed in the appalling service received from Wesbank! I am trying (without success) to make regular additional payment for capital reductions to my vehicle loan, an act I think should be rewarded with good service. The problem however is that Wesbank seems to make it impossible for an individual to write off dept in a shorter amount of time. I start the process by transferring money into my loan account which then automatically reflects as an advance payment (without any other options). I then email Wesbank services to take the advance payment and make a capital reduction in order to incur less interest on my loan (asking to be contact for details and leaving my number). This is then where it goes sour: For the last two months I have sent numerous emails asking to be contacted regarding this request without any success. I have also spent a total of 67 minutes on hold (also without success). This is utterly unprofessional and I just wonder who will be compensating me for the interest UNNECESSARILY incurred as a result of Wesbank's terrible service...

I regret financing my vehicle through Wesbank!
