After three years of continual back-and-forth with a bank over a mortgage adjustment, one would think there’s nothing that bank could do to surprise you. And then it goes and sends documents containing information that even an inept ID thief could use to rob you blind.

Luckily for one woman in Colorado, the person who received mail intended for her was not an ID thief, but instead a good and responsible human being.

“When he called he told me, ‘I don’t want you to think this is a prank,”” the woman tells CBS Denver.

This wasn’t just a case of the mailman delivering her mail to a neighbor. No, the person calling was thousands of miles away in Massachusetts.

And he didn’t have to do any digging on Google to find out how to contact her, because not only did the documents contain her entire loan payment history, but also her account number, full name, address, and phone number.

In a statement, Chase claims it “take[s] the protection of an individual’s information very seriously,” and calls this an “isolated incident.”

The bank rep also says “We immediately retrieved the document,” except — unless there are multiple copies of it out there — it didn’t.

No, all Chase did was send a letter to the other customer asking to return the documents. Rather than do that, the Massachusetts man sent both the document and that letter to the Colorado woman.
