It took me 3 years to sort mine out , In the end I paid 17 years back at a cost of over £13,500 .
I started phoning them up in 2021 , but it would take over 40 mins for them to answer the phone only to tell me to phone a different number.
Eventually they told me to write in , it would take them between 4 and 6 months to reply to my 3 letters. They could never explain why the online system showed i had 15 years of full national insurance contributions and 6 further years were in being looked into which would have given me 19 years. After buggering me around for 3 years in numerous letters and phone calls and 2 complaints I had lodged that never got dealt with. I eventually paid myself right back to 2006 which was 18 years that cost me £13,642 .
Then , they informed me that I still only had 32 full years and therefore would never get the full pension as you needed 35 for that.
I strated collecting my pension in March 2024 at the rate of £202 a week.
Makes me mad as if you spent your life on benefits like most in the UK , you would be entitled to the full pension.
