Had a number of calls from this number claiming that they were looking for "Vicky" but the story is always changing with variations about her daughter, someone called keith, that she got my nuymber out of the phone book for them etc but I have had an unlisted number for more than a decade. This person sounds elderly and does start to talk a little about themselves and some kind of problem issue that they have but then starts to ask me questions (that I refuse to answer) about what I am doing, when I will be home, where I live etc. Not sure if genuinely elderly confused person but does seem to be fishing.
