Misrepresentation, Failing to deliver & Bad Servic

I recently bought a Polo 1.4 from this dealership . I dealt with Salmaan the whole time, He was all nice and friendly and doing things timeously prior to the purchase as well as on the day that the deal was finalised and I was told that the card had never been in an accident. I was having issues with the car so I took I the car to three sources. I took the car for a 2nd Dekra inspection and it did not pass (how did it pass the 1st?) All issues that were found with the car were the same and confirmed that the car had been in an accident . Awaiz denied the proof. Now that they have my money, Salmaan makes empty promises and fails to deliver on all of them. They finally decided to fix the car after going back and forth and threatening to take them to the cleaners. I left the car for over a week with them and only a few things were fixed. I asked for the invoices for all the parts that they fixed and Salmaan keeps coming up with excuses as to why he cannot send them to me. I have been calling Salmaan asking him to send me the details and refund me but every time he says he forgets. Salman is very incompetent and I would not recommend Awaiz Exoticars to anybody. Worst service EVER!!!!!
