Bloody box tickers

Three years since I left the UK, and haven't set foot on British soil since. Shortly after leaving I filled in the correct forms, countersigned by accountants as required, to say I was no longer domiciled in the UK.

Look, you bone headed box ticking brain dead zombie alternatives to humanity, what do I have to do? I only have a Canadian tax return for that year which you won't accept as 'evidence' of tax paid, and as I completed a 'Non-domiciled' form back in late 2007 I don't have to (and haven't) filled out a UK tax return; which means no flaming P60 for the year in question! You never issued me with one.
