DISGUSTING CUSTOMER SERVICE!!!!

I got into a car accident on February 18th where my drive airbag dislaunched. Called auto and general and got the car towed away to a panel beater in PE while my claim was assessed. I was told I would be called by an agent to get my story and start the claim process. Waited a week and no call. Called the agent with MY air time, eventually cut and no call back. A week later I buy more airtime and call them again because I want this over and done with. 2 weeks later still no response. Eventually call them again and they tell me claim is approve HOWEVER they want to "fix" the car instead of writing it off. I say ok and they proceed. Its the 29th of april today. No calls from the panel beaters, not call from the insurance company, no updates on the car. I try to call I get told they will do a follow up and then nothing. The panel beater keeps telling me he's waiting for parts, for 2 month??? This is really unacceptable. At this point I don't even want the car back anymore because I don't know what this panelbeater has done to it while "waiting for parts". Your customer service is PATHETIC!!!!!! Just write the car off
