Incompetency and lack of urgency

My claim is in the 4th week and there is no progress on my claim. Ayabonga the Claim assessor assigned to my claim Is not even communicating with me or to even return my calls. Whenever I phone I am told that the team in still deciding. The claim is on 4 weeks and no 1 from PMD has ever went to view or assess the damage on the car. PMD ony relies on the pictures that I took and sent to them from the accident scene to arrive at their decision. Their processes are delaying the claim process and lack urgency and competency. I am not happy with the service I am receiving from them.
