Backing up, if you request a written claim and tell the customer where to send it and by when, if they don't do that on time provisional credit isn't required by you. You can't require a police report and I am hesitant to say they must complete a form you'll send them. Too much of their time is lost in you sending out a form.
In this case, what you described sounds like a loss to you. And don't forget that if this wasn't an approved access device, the customer has no liability, not even $50.
