Poor service budget

I was involved in a car accident(hit an run),my car got hit at the back with multiple damages, I am very dissapointed with the service from budget insurance,since the incident happen they never even bother to phone me an give feedback on the status of the claim,even to take the car for assessment I had to phone myself,now when I call them they say someone is busy with my claim but that someone does not give me feedback,this has a big inconvenience for me as I used the car to travel to work,it's been three weeks,and I don't know what's happening it's pathetic and really annoying dealing with them as i do not even have a designated person to deal with,every time when i phone it's a new person to talk with.
