POOR SERVICE/ OR NO SERVICE AT ALL

I had an accident on 10 May 2015, and made my claim on the spot. At first I was told that my car was fixable, so I waited. about two weeks later, I was told that it was uneconomical to repair, so they started investigating I don't know what. The insurance company apparently appointed assessors to assess my case, I waited a long month. I followed up with the assessors, they sent the report to the insurance co. and I was later told that it will be fixed. so I waited further. today, I decide to make a follow-up with the panel beaters only to be told that it was written off long ago. No one bothered to inform me, I had to find out for myself. I will be paying my fourth instalment and third insurance premium without a car. the service is poor, they don't bother giving feedback, but they never delay on deducting their premium. right now, I don't know if I have a car or not because one day its fixable, and the next day its a write off. HOW LONG AM I STILL GOING TO WAIT???
