Pathetic Service and Lack of Communication

I have a claim that's ongoing with Momentum with no feedback from the assessor. I've had to use HELLO PETER previously to get their attention. The assessor in the past made comms on the same day as the complaint but went quiet since then and its been more than two weeks. I've left messages and sent emails but to no avail, my broker who is a Momentum employee also cannot reach the assessor. It seems that this company operates with no empathy towards their clients and have a lack of commitment to their loyal clients.
