No idea who they are but they have tried to ring constantly. I ended up answering it this morning and they asked for my mother - to which I said that it was my mobile not my Mum's.... So not sure why they are aksing for her. They said 'I'm sorry i will remove this name/number from the database'. I then asked who they were and why they were calling to which they said 'due to the data protection act I cannot say why I am calling someone else!!'
