Unhappy with Wesbank

I bought a vehicle through Wesbank however the vehicle had issues from day 1 and eventually broke down in 2 months. I informed Wesbank that I wanted to cancel the deal instead they referred me to the Ombudsman. It's now 6 months still no assistance and vehicle is at the dealership and I'm still paying for it. I'm told that I need to wait for the ombudsman and the dealer for outcome.
