Very bad and poor service

I am so dissappointed with poor and bad service that i am currently receiving from Discover insure and Dals libertas. My car as knocked by a rock underneath and the steering rack got damaged. I informed my insurance which is Discover insure on the 05/03/2028. They instructed me to take it to Dals Libertas. Authorisation was granted on the 20/03/2017. My car is still there they keep on telling me that they are waiting for steering rack. They said they noticed later that my steering rack is damaged. I dont beleive that because the reason why my car is there is because the steering rack was damaged. I'm suprised because it was assedsed by them. How can they notice damages later. It is their negligence and that is affecting me now. What frustrates me the most is that i dont have a car now and travelling to work is difficult for me without a car and that is why i have insurance. I had a courtesy car. Its term was extended with 10 days due to delays. Its expired now. I had to return it back. I've been phoning Dals Libertas and Discover insure trying to solve this problem nobody seems to care. They dont even respond to my emails. If it happens that someone answer my call at their customer service they let me hold for more than 15-20 minutes or untill my airtime got finished an nobody will get back to me Its really frustrating.
