You can't make this up

It's too bad that this happened.
The best you can do at this point is to get a check from the place's insurance company and buy the parts yourself, and either fix it yourself, or find someone that will fix it with all of the parts in hand when you bring it to them.
Make sure the check is generous enough to cover the costs and a bit more for your trouble.
I know it's a hassle, but it seems that's all you've got right now.
I hope this doesn't cause bad blood between the two of you...
