Long story short. DD was born just after this scheme started in 2002. DH and I can't remember anything about it, have no paperwork from the time. We left the UK in 2004 to live abroad. Dd is a British citizen if that's relevant.
Wrote to HMRC last year to ask them to find it. Received a timely reply asking on for more info which we sent last June. Received no subsequent reply from HMRC despite following up. Everything done by post because we can't get access online and dd doesn't have a NI number.
There's no phone number or email to follow this up with a human being. What can we do?
