Bad service

I brought in my Kia Rio 1.2 that I bought from Kia Northcliff about 2months ago, and since then I get a new problem on the car each time. I spoke to the guy from the workshop that the car is making a funny sound at the back when I am driving, I was then told that the problem is with the tyres and I needed to replace the tyres, but my question is, was I not supposed to be given tyres that are in good quality when I bought the car? I would understand if I had to replace my tyres after a year, but 2months is not fair on me a consumer. When buying the car, I thought I was going to get good value for money because you are a reputable dealership, but right now I regret buying the car because the more I drive it, the more faults I find in the car, these are not faults one can see by just test driving the car. And with all the reactions I am receiving from the dealership it does show me that the sales person Steve knew about all these issues and thought they wouldn’t be visible this early. It is very frustrating and a waste of time to bring the car in every second week, if I wanted all this inconvenience I would have bought the car at “Oom Paul’s Motor Dealer” but I didn’t and I am regarding it right now.

I have also been promised that they will re-aliened the bumper of the car since its was not properly aliened when I collect the car, two months ago but every time I go there am being told they will book the car to go the panel beater but it has been done as yet.
