Horrible service

I am very frustrated and angry and exhausted with how this company has been treating me through my claim process. I got into an accident in April and until now I fight with this company everyday to get my car fixed but every time I call no one is willing to help or they promise to get someone to call back but nothing. They pretend to understand but they are not willing to sort me out. What infuriates the most is that they sent an authorization with incorrect information about my car and myself. I keep getting information or notifications that I have booked in my car, they are busy with my car and I should rate the PANELBEATERS but I still have my car with me it makes me wonder which car was booked in for fixing. They should pay me out and I will find someone to fix this because its proving to be impossible for them to fix it.
