The fact that the Bailiff hasn't done his/her research is his or her problem. When it happened 5 years ago, I just shouted very loudly that
the was incompetent and asked very loudly what part of the sentence "HE has never lived here and I have no idea who the person is" that he was TOO STUPID to understand. So in the end passport at him that I didn't ACCIDENTLY take his eye out. Unfortunately I do not have the physical build to use reasonable violent force, so he got off lightly.

And to this point I have never received a written apology from his company for their criminal incompetence.

Fortunately, further incidences have not escalated to that level, but if it does in the future, I think I will just ring emergency services and ask to the police as I am being threatened on my doorstep. But I have no intention, apart from writing a "Cease and Desist" notice to the police service of wasting any more of my time following up correspondence apart from return to sender - not at this address on the letters, and if that result in escalation and harassment by bailiffs, I will be mentally prepared.

Anyway I'm getting very self-rightious here.....
