Car dealership

I bought a car in at Bidvest McCarthy Audi Menlyn in November 2022, i was told it was a demo that was used by one of their sales guys. My sales consultant was Neo firstly she **** about the kilometers on the car okay i let that slide a few weeks later i noticed that the drivers seat cannot be undusted i took the car back and it was fixed. Fast forward to May 2023 i took the car in for a service with other minor technical issues that were a concern, i was told that the reason for those technical issued are caused by the fact that the car was in an accident and had been repaired in the front . I was shocked because i have never been in an accident with this car i only had a small bumper on the back which i acknowledged to them however the front part i know nothing about and the only explanation is that i got the car like that , i even produced pictures to the service consultant guy "Jay" of the car that i took the same day i took delivery of the car after i got home and he confirmed that he can see the damages on the pics . Now they are telling me i am lying i got involved in an accident and fixed the car now i claim that i got it like that . All i am asking for from Bidvest McCarthy Audi Menlyn is the pictures of the car before it was sold to me then they can say i am lying . The service from Neo has been **** from the beginning anyway so i wouldn't put this passed her .
