Worst insurance company

On 24 November 2014 one of momentum's clients drove into the back of my vehicle while I was on my way to work in traffic. To date they are refusing to pay for my damages suffered whilst their client had full comprehensive cover & their clients claim is long settled while I have to get the back foot. The asked me to take my car for assessment during....and made a booking, when my driver got to their assessor he was advised to go home as no assessment was booked for my vehicle & it would take 4 days to have this sorted, I had to phone and fight with them and their assessors to have the vehicle assessed immediately as the booking was confirmed. Alomost 12 weeks to date & after sending numerous email requesting feedback - and with no responce I called the consultant and she them advises me (with a bad attitude) that the claim is now with another operator who is now on leave & i will have to wait till that operator is back from leave. Momentum is collecting money from their client for third party liabilty but now dont want to pay. This is the worst service.. Momentum! please pay for my damages as I am tired of dealing with your incompitent consultants.
