I’ve opened a case to get my vat on fees refunded. SS have asked for an HMRC letter confirming I am a Sole Trader. HMRC advised me they are not allowed to do that. I have a recent letter requesting confirmation of a UTR number that I was going to send to Amazon. I’m now stuck. Can anyone help. I have my tax return I can send as requested.. I have paid over £5000 VAT on fees last 4 years. Goodness knows how many thousands before that. I can only claim 4 years (statutes of limitations)

Please read below portion of Amazon response/requests.
