Disgusting service from Hyundai

I am a loyal customer to hyundai pinetown. I have purchased 6 cars from you. I recently bought a grand Creta 1.5 3 months ago. It started giving problems, the engine was making strange sounds.,reverse camera goes on when the car is parked. I took it to Newcastle Hyundai before checking the car they asked where do I fill fuel when I told her where I fill they indicated that was the problem. This was before they checked or tested anything. After testing they said their suspicion was correct. I received a certificate from the garage clearing their diesel. Hyundai Newcastle decided that the diesel be sent for forensic testing but they will not for it as the car was bought in Durban. Hyuandi Durban requested the diesel be sent to them for courier testing. Both branches are refusing to give me a courtesy car and refusing to pay for the deisel forensics. They are finger pointing. This is very frustrating as I don't have vehicle. If don't contact them they will never call. I have to keep chasing the guy in pinetown and Newcastle. Many people have convinced me to get a vw or cherry but because I am a loyal customer I chose to ignore them. Now I am the fool for not taking peoples advice and trusting you guys. Pathetic service is an understatement when it comes to Hyundai. Previously only drove VW and never had any issues. Unfortunately I am used to hyundai pathetic service because it took them 2 months to get my daughters kona registered Newcastle Renault had to intervene and get her sorted. Now I am expected to pay for the diesel test yet took so long to register my daughters. It also took them very long to license my creta. Of which I had to call every single day for feedback. They do not call and keep u updated. I have to call. They are not serious and don't care how incomvenicing this is for me with no. They just don't care. This is definitely going to be my last hyundai for my daughter and I. Will never recommend hyundai to anybody!!!!!
