Unresolved claim

Goog day, I launched a claim on the 7th October which was authorized on the 12th. From that day the panel beater chosen by way started working on the car. In they beginning they used to update me on the progress but for the past 3 weeks I do not get any feedback from them irrespective of the messages I left for them. Then I have been calling my way to intervene since they are the ones who took my car to that workshop but every time in call the call center(claims) am told my matter has been referred to management which never gets back to me. Now I need you to help me get my car back to the panel beater since it has been over a month now with no car and advise me on a way forward.
