Absa unable to resolve my issue

I would hereby like to lodge a complaint of unfair treatment and no resulution towards a concern with the Absa vehicle finance. I bought a vehicle that is financed and approved through Absa, no later than the day of signing the contract the vehicle broke down on my way home, I therefore contacted the dealer which towed the vehicle back to their premises and later directly went to Absa to inform them that the contract should be cancelled, upon my arrival I was told that there is nothing they can do about it, I therefore made means to get through the customer centre and managed to find the contact details of the person who approved the deal. Shockingly enough when I explained my situation to the person, he told me that he can not cancel the deal from his side and has to wait for the people from the dealership to cancel my deal.
