Been receiving a few letters regarding a debt that is intended for the guy who lived here before me (a black man sounding name, I am not black). Most recently I got one today mentioning it was a "final notice" and if full payment is not made immediately goods will be removed for sale with "after 7pm today" ticked below. Now from what I've found out this is complete scare tactics and they're not allowed to enter the property without a court summons if I'm not mistaken. If they come around later do I need to prove who I am/what's the best way to get rid of them for good?
