So I've lived in my house for two years now and the amount of mail I get for the past owners keeps increasing. Last year their passports arrived, I get what look like bank and credit card statements, post them all back address unknown. A couple of those that I have accidently opened have been from debt agencies/final reminders.

In the last week I've had a number of messages from Barclaycard to call them. I'm at home today so I answered the phone when it rang and they asked for the guy who used to live here - I told them he was no longer here (and BT give you the same number as the previous people had at the same address if they don't take their number).

I'm returning 5-10 pieces of mail a week and now phone calls. Are they using the address to run-up creidt or something? How can I make it stop?
