Not a happy client

Not happy with the service I'm getting from MMU Lephalale, been trying to get help with settling the car that I have traded in in June till today the car is still on my name and last month the car got a traffic fine which came to me as the car is still registered to me. I was told that once the installment for end of July is received by the bank that was financing me the settlement will be sorted. All I'm being told is that the issue has been escalated but with no feedback received. I have escalated this issue so many times. How long will it take for the car to be paid up because this is causing an inconvenience to me?
