Unhappy and disgruntled, still waiting for feedback!!

In trying to contact NetAssess, I wait for a long time to speak to a consultant, then my call cuts. When I eventually speak to someone, they provide information which is different. They promise to give me feedback, and then dont. When I contact Momentum, they say that the feedback they receive from Netassess is different to the feedback that I have received. To date, my vehicle claim is still stuck and I'm flipflopping between NetAssess and my insurance. They're blocking my claim for I dont know what reason.
