Motor dealership lacking customer service ethics

I bought a car from them in February 2026 at Auto Addicts Commercial Road The information on the description board was false. The worse part was when I took the car for road worthy and the engine number didn't correspond with the body of the vehicle. The manager treated me so bad, the floor salesman was worse. Since buying the car I drive it maybe 5times to date. There's a lot of mechanical faults that they , say is excluded because they make you sign an buy as it is agreement. The manager oh my word if never came across such a disrespectful, cold, inconsiderate human being. They now expect me to take the vehicle to them at my cost in order for them to take it to clearance. I have been without the car for almost 2 week now because it's not driving. They care less because my money is in their account.
