For a while now (a potential corona virus infected) person has been leaving messages on my phone asking me to phone back (no chance) to arrange a time for him to do a insulation check on my house. Today I got a letter (to the occupier) not my name and not giving a date for a visit but asking again for me to phone them to make an appointment, fishy or what?

Well I have no credit on my phone and they can’t force me to buy any!
