Sorry for delay PottyPrincess, I'm sure you're not potty though.
Yes I was accused, like you, of drawing benefit when working but at the time the word was just a few hours a week. I also worked in the EU unofficially.
I was so angry because, I wasn't doing anything wrong but the person who I spoke to was like one-eyes, you know, can't see anything but what she thought she knew.
After I went to the MP and the paper, it was dropped within a week. I told them they were clearly working on inaccurate information and refused to consider this. I then said that I would no longer try to give this information to them, as I had tried already without success, and it was refused but I would (and have) provided this to my MP and the newspaper. I did not give my MP's name nor the newspaper name.
I got a letter (very standoffish and unfriendly) saying the matter is now dropped and no interview will be required. My benefit however has stopped.
One person who helped me sort it out works for a lettings agency consultancy, who provide lots of services to help both agents and landlords, anyway they are on the side of tenants too. I was renting.
Hope you get somewhere.
