Phone number to call to allocate NI catch up payments for overseas resident ?

HMRC team (or other knowledgeble forum users) I am an overseas resident (Canada) I have completed a CF83, to establish what I need to pay to catch up on NI contributions I have received a response and have paid the stated amount. This was almost 4 months ago. I have confirmed (+ 441912037010) that the money was received and is awaiting allocation. The agent on this number could NOT allocate my funds to the appropriate years on the call. He says that has to be done by a different department. My question: What Number can I call to get an agent on the line that can allocate my confirmed payment to the appropriate years (06-24) and hence update my contribution record and pension forecast? Thankyou in Advance. Jonathan.

Hi,
It’s currently taking about 22 weeks from an individual making their payment of voluntary National Insurance contributions to it being recorded on their Personal Tax Account.  Apologies for any inconvenience:
