Thank you.I will copy in the ICO then as one of the things I have raised in my letter them is the source of their information. Where exactly did they get the idea that Mr X lives at this address? I have made a comment about my right to data privacy so maybe it makes sense to report them to the ICO. Is it a little cheeky to include an invoice for all my time and money (registered posting etc) spent on this? I guess they will just ignore it so is it worth even doing? Someone suggested doing it to show them I'm serious but perhaps it will just make them laugh at me - what do you reckon? Once again thank you for all your advice. What wonderful people you all are!

Thank you for the advice. I have informed them several times that Mr X does not live here. They just send more letters! LIkewise, when I return to sender. But I like the idea of copying in the Information Commissioner - do they have any legal clout? Also, I have been trying to find a sample of a cease and desist letter but can only find American ones, that refer to American laws and agencies. Do you know of any with English references? Thank you!

Hi I just stumbled upon this thread purely by luck and I am hoping that one of you can give me some advice please. Wescot have decided that Mr X lives at this address and they keep on sending me letters saying that he lives at this address, that he owes money and that they are going to take action to get the money. However, Mr X does NOT live at this address and never has (it's a new house so I know this for certain). I have sent Wescot letters saying that Mr X does not live here. They acknowledged that and claimed that they would send no further letters or requests for money but they have. Each time they send another letter it has a different reference number on it. They claim that each time the company they are representing passes another bill to them, a new reference number is generated and a new letter is sent. Because of data protection laws they say they cannot cross-reference the different reference numbers so theoretically this could go on forever. What can I do to get them to stop? Thanks
