Unhappy customer

I bought a brand new dodge and have had some trouble for over a year .The reverse camera keeps on playing up .About a year ago I sent the car in for a service and told them about the camera it’s been a year now I was told last year that a new one had been ordered still nothing I have even contacted the company that brings the cars in but still nothing.ive now been told that the car is out of guarantee and no order was done .ive been called a **** and was told the videos I keep taking or not even in my car . What do I do now can anyone help me pls . I have so much footage trying to reverse I was also told the system needed an upgrade that did not work. My next thing is the car was pulling to the left I had to replace my tires after about 10 000 km . They said there was something loose on the one side but nothing about who paid for my tires . Last think in the first couple of months a light came on I called dodge they told me to stop the car and not drive the car went in got it back and was told it was an electrical fault . Dodge why do u hide when I’ve been in to chat to the principal dealer in Tokai. Unhappy customer Neil Doveton.
