I had an accident in March this year and claim was approved

I had an accident in March this year and claim was approved. But the sent Auth nr to the wrong dealership. And only sent it where my car was at after 29 days. I finally got it and car was repaired. When I fetched it in May it was in a Friday. I realized it is not driving well. I could only take it vack the Monday. I took it in, and after almost 2 month no one from miway has called me. When I went to the dealership to find out last month if they heard anything, I was told miway did respond and in an email (which miway did not even Cc me in) Isaac that they suggested that it might have to be written off. Because the machenic conformed to miway that the Top gasket had blown. When I called miway I was sent from Pillar to post and nobody wanted to take responsibility. And till today miway has not called me and for all these month I am paying for a car I am not even driving
