Carvana complaint: accident car

I do not not want to put my frustration out on you but I am tired of dealing with carvana and silver rock. If you look thru my account you can see how many times I have spoke with someone and called and I have not gotten the help I needed yet. Last week I called carvana regarding this issue I have had with my car. They told me to call silver rock and have them to cone. Silver rock keeps canceling my appointment. because they are trying to charge me 50 dollars. My warranty is almost up again. So I have the email where they sent me this morning canceling my appointment. when i first got the car I called regarding the issues of the car they stated i could bring it back but I will have to pay for the extra mileages which was going to be 1000.00. so I decided to keep the car and get it fixed I had an appointment with silver rock the guy came out and checked the car but he said he couldn’t fixed it because of the paper work and too call carvana. Which i did. Carvana told me to call silver rock. I have been giving the toss around since I got the car No one wants to help. every time I message on here they tell me to call. When I call Nothing seems to get resolved. The warranty is going out. My car has not been fixed in 3 months. I pay my car note on time. the car was in an accident before I got it. I’m so over carvana at this point. I just feel like no one really cares. they can take my money but cant get my car fixed. Its not fair I’ve been patience and nothing is working.
