Amazon, possible scam.

So Amazon has been trying to call all afternoon to verify a $999 phone purchase but for some reason I kept getting cut off. Finally I just spoke to someone who seemed concerned that my account had been hacked. I decided to have a little fun by pretending to have multiple accounts and needing to know which account it was charged to, thinking no way will they come up with a name. Boy was I wrong, the woman on the phone managed to come up with my MIL's name. Problem, she passed away a decade ago and never had a cell phone nor an Amazon account.
