Lack of service, support and overall a bad experience. I wish they would take accountability for their mess. I'm furious

I M disgusted by the lack of service recieved. My car was in an accident on the 31st of January. FFW only sent my car to the panelbeater on the 6th of Feb, and gave authorization on the 11th. Parts were only ordered on the 21/2. The courtesy car had to be returned today and I had to constantly call FFW and escalated this to multiple departments they still haven't called me with feedback. I've had to pay a substantial amount for the rental car to be extended. Several calls were logged and recorded if there is any reluctance to dispute the matter. The case manager has been pathetic I only heard from her once or twice. I pay insurance for a reason
