I found out this evening that the old tenant from my house has been using my address to take out store cards and credit cards (it's been over 3 years since he lived at the house so they are definitely not old debts). A debt collection agency were at my house when I was at work and on the note he put through my door, it basically said they would enter my property whether I was in or not. Now I'm terrified that someone is going to come to my house and take my stuff when I'm at work.
I'm also furious with the old tenant and managed to find his address on google - apparently last year he was declared bankrupt. Apparently, it's not technically against the law for him to be using my address in this way, until I suffer a financial loss.
I have done everything I can and reported the matter to action fraud, emailed the debt collection office and tried to call the number on the note through my door.
I feel so angry though and have an overwhelming urge to go and find this man and confront him. He has caused me so much stress and work over the past 3 years as I've had similar problems before (bailiffs and police have been at my house over unpaid fines) and no-one in law enforcement is taking it seriously.
