Poor after sales support

Well, last year June, I bought a car. Everything went well with the bank and the team in collaboration to ensure I get a car quickly. For that part I will always be grateful. However, my concern started afterwards having the car for few months. My intention when I bought the car was to have something I can use without having to be in contact with a dealer regarding issues of the car. Unfortunately, this is the issue I am dealing with at the moment. When I bought the car, I was told they misplaced the service book. Upon further enquiry, I was told it was nowhere to be found and there is nothing they can do about it. What happens when I need to sell the car? the admin due to having a service book. Another issue is the smell when I use the fan. I went there to resolve the matter, later I was told I need to go a one of the dealers to sort that out. So, a customer needs to go up and down to resolve this issue while it should have been fixed by them. Lastly, I keep getting noise when I brake, not sure if it's the brake pads or not but it's annoying. The after-service support is just so concerning. If you are to consider buying your car from there, proceed with cautions because at a later stage you might be the one to deal with problems while they have made the sale. I am really disappointed, and I had to write this review so that others may not have to go through the same experience as I did. Buying a car is a huge commitment, and to have this kind of after service, to me it says nothing other than not taking customers serious like a car sale is the same as grocery sales.
