Bad service

I had an accident on the 04/06/2015 and my car was taken to repairs by the midway insurance. After they painted the car it turned out that it has two colours. I notified the insurance and they send their assessors and inspectors to check on the car and they haven't given any feedback. Every time when I called them they are always say in they will get back to me.Today some lady called and said they will send the assessors I sent know how many assessors should assess .
