Pathetic Service

Pathetic Service. My car is at the repairer for about 2 weeks already. Integrisure is refusing to replace items damaged in the accident. I was advised by the assessor that the items were approved and when i called to follow up was advised that the same items were now disapproved. A lady by the name of Sonja was the one who disapproved the items. She is not returning my calls, and promises made by staff that she will call me does not materialize. I would like to know based on what the items were disapproved. I have never dealt with a company who lacks customers service like Integrisure.
