Failure in delivering service

I had an accident in late December last year and logged a claim with Momentum. My claim was approved 21-01-2015 and sent to their panel beaters (Autotech Newcastle). Up to date I haven't received my car back. I followed up with their panelbeater and they said to me they are waiting for Momentum to send them another assessment report (second one). The guy in panelbeating department avoids my calls and even Momentum now is not giving me a clear indication of when will i get my car back. It's almost 2 full months now and I've been paying them as usual.<br> <br> I'm starting to suspect there is foul play here because the panelbeater told me to ask my insurance, when I called Momentum they said I should follow up with the panelbeater. No one is accepting responsibility but sending me from pillar to post.
