Oh hell any of the options that cause the company some pain for:

1. Being sloppy with a weapon
2. Copping attitude
3. Not even saying thanks

Call the ATF, find out what the requirements would be to have the weapon transfered to you. Maybe I'm just a bit more devious than some, but there is a bit of karmic justice here.

At the very least, get it to the ATF and find out for us what they plan on doing, should be entertaining at least!
