Bad service

I bought a car at imperial last. It give me problems. This year I wrote a review, on hello peter and imperial called me and apologized and asked me to bring my car in January 2018 so that they can fix it. They can't seem to find out what the problem is. My settlement amount with the bank then was R58000 the manager by then said they will pay R30000 and I must pay the balance. So I went and did a loan for the balance, I went back early March to find out the statement amount and find out how long will it take for them to take they car back. To my surprise the manager who was assisting me no longer worked there, there was a new manager. I had to start again and tell him my history. This was early March, the new manager said we can't continue with the deal till he knows the problem. My car is with imperial its not starting they also don't know what the problem is. But no one calls me to update me, I need to keep calling them and following up. My car has been at Imperial select the Glen since January, its April now and they still don't want to give me a solution. I am still paying a monthly instalment for a car I don't have. I am tired of this I have been fighting about this since last year. They not being helpful, they just continue making a fool of me. Imperial select the Glen is bad news
