Admin help please. I have an A003 issued 02/10/2023 that HMRC cannot find on EESSI RINA system

The french URSSAF put an A003 on the EESSI RINA system on the 02/10/2023 and it is marked on the system as received by HMRC. I have called and complained numerous times but I am told by HMRC that they cannot find it. After an urgent referral a Manager does not call me back within 24 hours.... they do not call at all, nor send me an email. The URSSAF are not going to re-send the document, but they have sent me a copy printed from the EESSI RINA system. I can send that to HMRC NI if they would contact me by email. I am now without an A1 or S1 for 3 months, so no income and medical bills not reimbursed. Please let me know how to talk to a manager and resolve this issue. David.

No-one....? I spoke to a manager yesterday (maybe, it could have been the person at the next desk) and they promised to help and call me back themselves later in the day. I have come to the conclusion that it must be HMRC NI official policy to lie to "customers". It cannot be that all the people that I have spoken to took the initiative themselves. It seems that I will have to instruct lawyers. David.

Hi unhappy Kent,
Can you please contact the National Insurance international caseworker helpline and inform them you have not received the managers call back so they can investigate
the matter and advise you.
If you have access to a Personal tax account, you can use the webchat service or call:
Number - 0300 200 3500
Overseas - +44 19 1203 7010
Open - Monday to Friday: 8am to 6pm, Closed on Saturdays, Sundays and Bank Holidays.
Thank you.

Thank you very much for your reply. That is the number that I have called almost every week since September 2023, asking every time why no manager ever calls back. I have requests and complaints dating back to September that have been marked as "completed" without any correspondence whatsoever. I had no revenue or support during the pandemic, and the loss of the right to work due to this administrative error has prolonged the difficulty. I have asked for transcripts of all the calls. In the meantime I will be forced to declare cessation of activities and take retirement in order to survive.
