Wesbank terrible service - extended maintenance policy

I recently bought a car financed through Wesbank. An agent phone me and offer a maintenance extension on the car of which the cost will be added to my premium, he also promised to send me the policy number with the terms and conditions. A day later I received a notification from Wesbank that my premium is going to increase, to date still have no terms or conditions, policy number or anything. Terrible service, I can just imagine what will happen if I have to take my car for a service.
