Timeout

UPDATE - Just called the HMRC as advised by NI Helpline and payment has been received. It was only a 20 minute wait which is shorter than it takes to get through to my GP. It will be allocated to my Pension account today I am told,

Thank you for the information the reply is much appreciated.

I paid 4 years voluntary NI contributions on 2nd March 2022 by bank transfer to improve my Pension Forecast. The gaps in my NI record have not been updated yet. How long should I wait before calling to see what is happening?
