Dissappointed and disgusted

I am very disappointed with Auto & general, when they advertising they lie and say they will support you through out your claim. My car has been with Renew-it Bedfordview since the 06th of June up until today I don't have my car back and the panelbeater service advisor and management are giving me updates that are going backwards and forwards. I have been trying to get Auto & general as my insurer to help me but no one knows what to do. I have asked for management I have been kept on hold for 30mins for the past 2 days
