Overpriced car showing Defects

I bought a used Toyota Corolla 2018 model from Lindseysaker Midrand on the 19th Nov.. I picked up several defects on the car 7 days down the line as the vehicle was took forever to be brought over... Car has 3 different white colors.. Front and Rear bumpers were re sprayed.. So as the boot-lid was also resprayed as the boot has to be slammed abit harder... The car's alignment isn't stable and shaking... Driver windows rubber fell off.. Rattling sounds on door panel.. I've laid a complain to the dealer which the sales person who conducted this deal Abel Ramolotja ignored my mail then eventually I got hold of Kobus Krill who's a line manager... They took the car in for alignment which was never fixed properly.. They also called Toyota to replace that rubber... And try sort the rattling sound which is still there... I've asked them did they acknowledge that the vehicle was resprayed which Kobus Krill responded they were not even aware about it as they didn't check the vehicle in question... So I went back to them to ask how did they price the vehicle that wasn't checked because i was charged 180k for a vehicle Toyota is now weakling to take it for 135k based on its current condition.. I've also escalate this issue to Gregory Sepolwane Principal dealer who's not anywhere near helpful... Kobus Krill further said because Trans Union report doesn't show the car was involved in an accident.... They didn't even assess the vehicle on arrival.... So my standing question is how did they price a car that wasn't checked to begin with... The vehicle has 38000km currently.... I don't understand why would they feel liable to fix a car that has wear and tear warranty on it.. I haven't started paying this car yet hence am not happy with the condition as it has already failed assessment tests.... I feel ****** of the whole deal as I don't think the amount charged for this car is even worth it... Kobus, Abel and Gregory have failed to give me reasoning on all questions asked... I need guidelines on dealing with this people....
