No feed back on my car

I had a minor accident with my car on 2nd of October and my car was towed to fleet VIP solution as per my insurance plan. they only found out it was in their yard 2 weeks later, took another week for it to be assessed and I have had to keep on calling for follow up and never get a clear time line of when my car will be fixed. That Is of I am even lucky enough to get someone who can assist me. Moat of the time who ever needs to assist me is said to be busy and will call me back which never Happens, this has happened more than 5 times. I have now been without my car for about 6 weeks, has been very frustrating, I wish I had taken my car and fixed it without involving insurance and fleet VIP solution.
