Warranty claim rejected, ref (OC***)

It's my 2nd time writing here and without any help, I am not happy with Renault, my car was not fixed and it is still under warranty, everyday I get different stories since last week, so now I need 1.assessor report 2. I was told warranty rejected my claim because my car was not serviced last year, I need that respond sent to me via email, and it must state if I did serviced it last year it wasn't gonna have that fault, 3.I need what was qoated, and the reason why they rejected. 4. My car did not have any problems with sliding until it came back from the dealership. 5. I service my car every December(check service book) so the whole of December my car was at dealership that's why it was not serviced, 6.i need all rejected reports for my car so that I sent it to ombudsman. According to my understanding my car it's still under warranty if it's broken it need to be fixed, every month you guys debit, I'm paying to drive a car that is giving me problems? I'm paying for the car that is always at the dealership? I'm paying to put my life at risk with the broken car, I'm not happy, my car has been kept for days without any positive progress. Im not gonna fetch my car until I get all the reports that the dealership was telling me, 1st they were forcing me to change brake pads and the problem was not that, threatening me to pay because they checked my car and I refused to replace brake pads, everyday it's a new story. I'm done talking ombudsman will do the talking for myself, and please I'm tired of your calls, any respond from you send it in black and white via email. Because telephonically it's not working for me, I just get lies.
