Just wanted to see if anyone has any advice really.. yesterday had a weird phone call from a withheld number, was a man saying I was selling something, I told him I wasn't then he said I'll come round at 5 I repeated I wasn't selling anything then he gave me the address I lived at 3 years ago! I asked where he got my number from and he said google .. was weird he was quite menacing. Then today someone has tried to change passwords on my Facebook account and my Argos card. I can't think of anyone that I've upset and I moved from the address he gave me 3 years ago but he knows my name and phone number. What should I do ?
