Allocation time for payment of backdated voluntary class 2 NIC's

Hello, I made a bank transfer payment for 5 years backdated voluntary class 2 NIC's on 12th January 2024 using the 18 digit reference number provided by an advisor on your helpline. I made it clear what years it was to be allocated to and the advisor gave me the total amount to be paid. It has not been allocated to my NIC record yet. Please would you let me know what date the manual allocation team are currently working on for backdated voluntary class 2 NIC's? Should my payment have been allocated by now? Thank you.

Hi Lightbulb M,
The timescale shows that self-employment services are currently working on post dated 29/5/23.
Thank you.
