a BIG NO to Arnaold Chatz - Bad CARS

Bought a Demo model car from Arnold Chatz car Constantia. on hte day we took the car, everything failed, ABD, EBD, SENSORS, Wipers, everything. I asked if i could return the car and cancel the deal, was told NO. So i took it back to them and also pointed out the scratches and broken mats in the car. there was a lot of scratches on the bumper at the bottom, this is still there, not even an attempt to buff it out from the dealership. this morning I noticed what looked like a panel at the bottom of the car is pulling loose. Went back to dealer (this is me having the car fro less than a month) and was told, i must have bumped the car :-(. I am so angry, they are useless and have NO after sales service. I understand a demo is not new, but this car still has a warranty. it is their duty to meet their obligation, especially because I cannot return a faulty car. Be-careful of which dealerships you use, they are chasing commission wit no interest in you.
