Very Bad Service and Commination

Very Bad Service and Commination - I took my vehicle in as an insurance claim for a bumper repair. They send me a notification that I can bring in my vehicle. I got there and the parts was not even ordered. I then had to reschedule and wait for the parts. Eventually after the bumper was fitted I realized it was the wrong bumper and I needed to take the vehicle back. They had a look and confirmed that the bumper was the wrong one that was fitted and assured me they will sort it out asap. It has been more than a month later without any feedback from them. Now that I reached out to them, they said but I can bring in my vehicle in. This is extremely bad service. I have notified the insurance company to hopefully take them off their panel of service providers.
