Bad Service

I am client of Auto and General my car involved in an accident as a client I reported to my insurance then they advised me to make a statement at police station it was on the 20/08/2019. Then drove my car to where I stay then the following day they called me and told me that the towing company will come and collect my car. When knockoff I found the guy waited me,it was late around pass five and to six. But the guy told me that because is late he is gonna drop off my car the following day at the repairing company, after he dropped off my then the following week I phoned repairing company just for updates. That guys adviced me of other damage that i was not aware of it. Then then following day i went to that company reason being wanted to see for myself. Then it was bad damaged at the right side at the back and even the light was broken,so had to do up and down to towing company asked them what happened to my car then they say their driver didn't damaged my car without consulting him. Finally later the driver said is gonna pay acces fee for piece sake just to keep client but he refused to have something in black and white. I reported my insurance about that matter then they said they are doing investigation problem they don't update me every day I have to call them. Since from that time and don't have car but every month they deduct the premium they don't care whether i have car even now they say they are investigating for the insurance my fixed my car then they will deal with that company because is the once they organized the towing company. For me Auto and General they don't care about their clients. May please intervene maybe they will help me.
