Rand Stadium Toyota No No!!!

On 31Januarie 2020 I bought a Mercedes CLA*** from Rand Stadium Toyota. When I collected the car I brought it under the attention of Rand Stadium Toyota that the gaps between the left headlight and the bumper was not correct. Also that the front bumper has body putty on and that the car didn't had any loose carpets in. The Salesman asured me that they will sort it out. I also there after brougt it to Rand Stadium Toyota's attention that the car had damage to most of the pannels, body parts etc. under the car. After inspecting the damage on a lift at the premises at Rand Stadium Toyota they told me after stating that that is what the pannels is supposed to be doing they told me they will replace and repair it. My car was twice at Rand Stadium Toyota for a few weeks but nothing was done exept a repair on a scratch on the driver side door that had to be repaired twice. Then I had to take my car back before the lock down. After the lockdown no one contacted me back. After lots of talk and me wanted to buy an new Ledgend 50 bakkie from Rand Stadium Toyota I decided not to do it because they went back on our agreement that we had on the price of a new bakkie. I told them that I didn't want the car anymore and I dont want to buy any vehicle from them and that they must take back the car and refund me. Now they tel me they will refund me and take back the Mercedes but want to give me R35000 less than what I paid for it because I used the car . How on earth???
