I agree with prior posters, pull the reports and see where it goes.
It might not be an AU thing, though - one of the caregivers at my grandmother's last residence before she passed took one of her credit cards, had the billing address changed to her own, and went Christmas shopping with it to the tune of $4800. She didn't authorize herself or put her name on the account anyplace, she just took the card and hit Walmart, Target, the mall... banking on the (completely normal) lack of salesperson interest in the true identity of the cardholder. We caught it when we went online a few weeks later to pay the monthly bill for medication delivery, which was billed to that account, and instead of the expected $450ish balance, it was over five grand. We contacted Chase and disputed all of the charges, and they charged it all back. When we started asking questions around the residence they discovered the "new" address matched one of the employees. She confessed when confronted by the police. They charged her with theft and fraud and all kinds of great things, and as far as I know she's still on probation. We would've preferred jail, and my uncle offered to take her out back and help her see the error of her ways ... but the police declined his assistance lol
