It's sending things in initially that's the problem, this is the self-assessment department (penalty appeal, so can only go by post).
I've spent all morning on it so far - first I phoned HMRC and was told it definitely wasn't received and I should use recorded delivery.
Then I realised I did send it signed for, so I called back and they managed to find it but the line cut off before they could tell me anything else.
Currently on hold trying to get through again.
