ABSA GIVE A LIFE LONG LOYAL CUSTOMER BAD SERVICE

My partner has been issues with a car from ****ron motors in Boksburg on the 30/07/2015. A SECOND-HAND CAR MAY NOT BE OF THE SAME QUALITY AS A NEW ONE, BUT IT SHOULD BE BE REASONABLY RELIABLE AND FIT TO BE USED ON THE ROAD WITHOUT DEFECTS. THIS CAR IS HAS MANY DEFECTS, THE CAR CAN HAVE A BREAKDOWN AT ANY TIME. WHILE DRIVING THE CAR ON 01/08/2015, HE FURTHER DISCOVERED THE CAR SUSPENSION IS NOT UP TO STANDARD AND IT WAS DISCOVERED THAT MANY CAR PARTS WERE NOT REPAIRED.He went to ABSA in Tzaneen to complain and they promised him that payment will be put on hold for the regional manager to look into this matter further. He was advised by ABSA BANK to take the car back to ****ron motors meaning the sale agreement is VOID. He RETURNED THE CAR on 04/08/2015, but now we are told that the deal is finalized while he has unresolved issues with the car ABSA financed him for.. The defects of the car are unsafe and life threatening! We requested to terminate the vehicle agreement with ABSA and FRANK SIBIYA HAS REFUSED. IS THIS IS THIS ABSA ETHICAL BEHAVIOR???! THE MANAGER HAS GIVEN US BAD ATTITUDE ALWAYS AND VERY POOR CUSTOMER SERVICE!
