I divorced 10 years ago. Lots of abuse of all kinds from him including financial which bordered on fraud. He has continued to harass and stalk me - me and my daughter last went to police about him at new year. Today a letter from Halifax bank came to my address (my house not his, last time he lived here was 10 years ago). It was addressed to him. It wasn't one of those things they send advertising their services it was saying his credit card was going to be renewed at the end of Feb and it had the last 3 digits of the card number on it. Could he have some sort of online account thats registered at my address? Should I be concerned?
