We've been in our house for nearly 7 years. We got a letter addressed to the previous owners at the weekend. Normally I ignore them as its junk mail, but this one was from Very so I opened it. It says that the previous owner of our house (or more likely someone pretending to be him) tried to get credit. It was refused because he is not listed on the electoral roll for the address. I am worried that someone is trying to get credit fraudently and it may result in our address being credit blacklisted. Any advice about what we should do?
