I forgot to mention this last week buy a guy I work with got a substantial tax rebate a month or so ago then last week got two letters saying he was due them money now, £500 more than the rebate.
He was on hold to HMRC most of Friday basically screaming g his N.I number at his phone getting the "sorry, I didn't quite catch that" back. He's from Cornwall, so it's not just Scottish boys they don't understand.
