Worst service ever

I bought a Car at Imperial Polokwane , the sales person there asked for support which i did give him. the car was delivered to me it had Scratches and dents and i pointed it out to him he said i should get a get and send it to them they will pay for the car to be fixed . i got the first quote which they said it was expensive they told me to go their other branch they have arranged someone to assist i did go and now they say the quote is expensive as well.there is no feedback from them ,The car is registered to the wrong address the sales person said i must change it yet they have charged me for that. is the a head office for imperial that i can contact regarding this bad service.
