I have also been pursued by Eversheds for over 4 years now and only stumbled onto this site a few months ago, so I am a bit of a novice as far as advice giving is concerned. At least you probably wont make the same mistakes as we did. I think a good place to start would be to read 'do's and don'ts' on this site and take the advice to send them a SARN immediately. Your second posting says you have 'filled out a SARN' - did you mean and I&E (income and expenditure)? I served a SARN on eversheds and was not required to fill in a form to get it. Mind you I had to wait in excess of 40days to get a response and only then got it when I asked the Information Commissioner for an assessment. They are in the habit of issuing ultimatums to respond within 7 days - (I cringe now when I think how we used to panic) - Don't worry about it. Include in your letter a request asking for copies of documentation to substantiate their claim. A list of what you should ask for is on this site as is a sample copy of SARN. Believe me, with Eversheds this process takes a very long time, we are repeatedly asking for copies. You are also correct in requesting them not to phone. They eventually stopped calling us but they still invite us to phone them.(posted 8171 days ago)There are many contributors to this forum who are far more knowledgeable than I am, so hopefully they will chip in a bit for you as well.
