Sir/Madam, I have lived outside the UK for 29 years. I plan to return for retirement in 2034. I have confirmed with the Future Pension Centre that I will benefit from shortfall make-up payments to maximize my state pension. I have made multiple payments totaling almost 2500 GBP since 3-June 2024, no payments are shown on my online NI Record page. Apparently (after talking again to the Future Pensions Centre) my ONLY option is to call HMRC, talk to someone directly, and have my payments allocated to specific shortfall years. I have attempted dozens of times in recent weeks to call the +1-44-191-218-3600 number to get this done, I call, I go through the security questions, I go into a queue, I get hung up on after 20-45 minutes of waiting, every time. This is not working for me, Are there any other options for me?
