FRANCHISE DEALER SELLING ACCIDENT DEMAGE VEHICLES

I had the absolute worst experience one could have buying a vehicle, contacted the dealership on the 6th of August , sales guy by the name of Aadil assist me , told me the vehicle is in a pristine condition and all that other sales bull**** . I made my decision , booked my flight for the 10th of August, he picks me up , got to the dealership, the vehicle was in a accident, not a small bumper bashing but where the vehicle actually has welding and body filler on it, can't explain himself ,but on the phone he was very "honest" he would never lie . I asked them to take me back to king shaka airport , they have the ***** to tell me no I must sort myself out . Where's the customer service? I spent over 6k in flights and Ubers for this ******* of a vehicle. The so called manager/boss couldn't face me running away in his office just like his salesman .
