2022/23 NI contributions record not updated

My pension is due to start payment in October. I made voluntary contributions up to the end of the last tax year (2022/23). The NI records for this year have not been updated yet, and I cannot check that my payments have been credited. The Department for Work and Pensions has written to me, stating that my pension would be based on a figure which assumes that no contributions were made in 2022/23. When will HMRC update my NI record & inform the Department of Work & Pensions so the correct pension is paid? I can get no reply by phone at all.

Hi Bridget Davies,

The aim for HMRC is for any Voluntary Class 3 payments to be allocated within 8 weeks of the payment reaching us.
If you have made the payment earlier than this, I would advise you to contact the National Insurance (NI) Helpline on 03002003500,
office hours 8am to 6pm, if the payment is shown on your account the NI agent will be able to allocate this to your NI record during the call.
Since the extension of the deadline to 5th April 2015 to make Voluntary Class 3 NI payments for shortfall years, the Helpline is no longer as busy.

Thank you.
