MG Dealership Manager refuses to engage with customer 4 months after sale of 2nd Hand Vehicle

bought a 2020 2nd hand mini cooper in January. Firstly the car had not properly cleaned when we took delivery, had damages to the lights which the salesman had agreed to fix but the dealership manager apparently subsequently refused to approve. the number plates both in the back and in the front had not been *****ed on and we had to take it back to have them to be *****ned on properly. Despite the dealership indicating that the car was serviced 2 days before we took delivery, 4 months later, the battery has died and the engine mountings have to be replaced (total estimate of necessary work is R24k) - this after a diagnosis by a BMW service center. The dealership did not disclose the above necessary maintenance work would be necessary, instead the car maintenance record indicates the next service is due only 12000km after the last service done.

worst of all, the dealership manager, a gentleman by the name of Riel (079 510 7608) has refused (not availed himself) to engage with me despite several efforts previously to speak to him - according to the salesman Jabulane Thebekwane (081 303 2725)
