We got a letter this morning, addressed to someone else at our address. The name was really unusual (almost sounds made up) and we happen to know the names of all the people who have lived at this address since the house was built, so I opened it. (not sure if I should about that or not).
It was a letter from a bank, thanking the addressee for letting them know his change of address, and saying that this letter was a security measure, sent to his old address (i.e. ours) to make sure he had made the changes himself.
I called the bank's helpline and they want me to send the letter in and are investigating. Is there a kind of fraud that could involve using our address but not our name?
