I have been trying now for over a year to update my national insurance record for 2022-23. My class 2 contribution was paid along with my tax via Self Assessment but the year is still saying year not full. I have phoned numerous times over the past year and I have been told there had been a computer problem and that self assessment class 2 NI contributions had not been transferred over to national insurance records. Each time I phone I am told my payment has been received and it is being processed and will appear on my NI record in X amount of weeks. I wait and after X amount of weeks my record has not been updated, I phone again and I am told the same things. How do I resolve this problem and have my national record updated correctly asap. DebM
