Good score on the voucher! The two times I did that I got no more than $35-40, this was described to me as their cost to have it delivered to my home about 25 miles away.
Good grief on the process, for something that must happen on a regular basis, you would think the procedures would be well known and applied uniformly at this point. You need to file a police report? The bag was stolen from THEM not YOU.
Good luck on it all, thankfully a total loss is pretty rare (but it must happen enough to standardize everything in one place for all to execute the same way.)
