I almost got in some trouble because of that. A "bank" I wasn't a customer of kept sending me messages about "urgent, answer this form with your personal details or we will lock your account". Seemed quite scammy to me. Then I later got a physical letter in the mail about the same, and then I called the bank. Apparently I had some account there holding some pension stuff from a previous employer. Shrugs.
