I don't see how they can claim that, 90% of the questions they ask are totally irrelevant to what I do. I am a self employed trader so the only thing that's relevant to them is the difference between what I buy at and what I sell at. Why do they want to know how much I sold my shares for? It was all done through PAYE anyway so they already know and it's absolutely nothing to do with the reason that I'm registered self-employed so if they didn't need to know details about it before I registed then why do they need to know now???
Add to that their web-site doesn't even work so they're gonna try and stick a fine on me for being late!
