Poor service from MFC complaints department after laying a complaint a month ago and daily emails begging for feedback but still none! !

Purchased a vehicle from a branded dealership Nissan, found out months later the vehicle had major accident damage to the value of R200 000 (purchase price of vehicle when I purchased it was R280 000). I contacted the dealer the denied any knowledge of accident history. I contacted bank to ask why they'd finance an accident damage vehicle that seems to have been a write-off that was fixed up. I asked about possibility of canceling contract as dealership is unwilling to assist. MFC said they can't really assist with matter as they only finance the vehicle and don't know history. Complaint specialist then escalated my complaint to DRM, dealer relationship manager I assume the acronym is for. I have been waiting for feedback for weeks. I have since had 2 debit orders go off to my bank for a car I cannot use as it has a coolant leak from previous accident damage. I emailed complaint specialist a week ago for feedback she never responded to any emails. I had to Call mfc to please ask her, complaint specialist, to get back to me. All she said was she has escalated the complaint. I am so disappointed. All the waiting without knowing if they'll assist me or not! Disappointing after being a 2nd time MFC client.
