Auto pedigree

Good day guys I come to you all with 1 broken heart as I bought my first car from Auto pedigree (randburg) on the 19/08/2020 and the car had some undisclosed problems and yet even today I don't have the car and the bank has to take its first installment this month and as we speak even at work things are no longer going as agreed and I tried to contact the branch manager to inform then about my situation and to ask them to cancel my contract but he said"No" as a young person I feel cheated as the manager had also made false promises before and now I'm being force to take a car I can no longer afford and was never given to me. I went to Auto pedigree hoping that as a big dealership I would have no problem with having car but now I regret the day I started my application with them
