Outsurance not responding to my claim.

My claim for third party accident, I was rear ended by an Outsurance insured car a year ago. they paid out the car that hit me with my claim details and claim number sent to me. They then gave me other documents to fill in and a new claim number, referred to legal and then a number of other people and now back at legal and no longer get any replies at all just ref. no. On top of all of this I am a Outsurance client, which will be leaving them.
