I'm SO unhappy to post this, but I highly recommend you get a solicitor to make a phone call or two.
A police friend of mine was swiped by another driver. The insurance would only pay for a used part that required three patches of bondo. My friend called me up asking for advice. I told him to threaten to turn this over to your attorney-friend. The same hour, they responded that they would find a fender in superior condition.
Then, they refused to replace his bumper. The bumper had been previously repaired, but this accident made the bumper unrepairable - bumper can be repaired only so many times before they aren't repairable. Their rationale was that because the bumper had been previously repaired, this second collision is not the cause of the bumper being beyond repair. So, they weren't going to replace it. My friend called me. I whipped up an email which I also used as my speaking notes. I called the adjuster's supervisor. We talked for about ten minutes. I explained in no uncertain terms that if this wasn't resolved, we would file suit. I also explained it wasn't personal either way, we're just both doing what we have to do. After hanging up, I immediately sent the email.
Gee, imagine that later in the afternoon, they settled to my friend's satisfaction.
I hate lawyers. I am one. I hate that people can't figure out how to get along without the threat of a dickhead like me arriving with the heavy artillery. But alas, society isn't as civilized as we might think. Until we become more civilized, there'll always be a job for me.
Stevo, go find a solicitor friend and have him gently suggest the consequences of not working with you. If they don't play ball, I highly recommend tactical nukes. Don't worry about any collateral damage, God knows his own.
PM me if I can be of assistence.
Cheers!
