Kia Dealership

This year I bought a Car at Kia silver lakes, as a first time buyer I felt that I was taken advantage of, when I bought the car as first time buyer or has experiences with car, the car was on 35000km, on the day that I went to fetch the car it was raining heavily, wasn't given the chance to inspect the car, I took the car home, the following day when I was doing car inspection for the insurance I realised the car had scratches, I called the sales person that was assisting me with the car to let him know the car has scratches on the right passenger(sit), he said I must wait he will speak to his manager to find out, after he came back to me to say that the manager says there is nothing they can do, I have already taken the car, okay I was angry but I let it go... And went to fix the car myself.... Come the time I had to take the car to the service, I was made to buy the service book which they didn't provide in the first time they were supposed to, I bought it because I was told they need to capture the information on the book, okay now I had to renew the disk licence that was expiring on the 31 August 2023 mind you I bought the car this year, I went to post office to renew the disk, when I got there am told that my disk expires next year on 31 Jan 2024, the disk is with the dealership they were supposed to give me the new disk which they did not, I can't go to the dealership to collect because I don't have much time I work crazy hours, I was told to go to the police station to get an affidavit and bring it back to the post office so they can give me a new disk and again guys I was charged for that. What KIA SILVER LAKES did to me is painful guys!!!! I don't think I'll heal from all the costs I incured for the things they should have explained when I bought the car as someone who had no knowledge of buying car!!!
