I filled in form cf83 over two years ago, so that I may pay back class 2 contributions, I have asked the pension department on phone about this, and they just say someone will get back to me. I live in france so not so easy on phone. I started claiming my small pension in March, I sent a long letter six months ago to hmrc with proof of french self employment over the last 14 years, now have filled out papers for small french pension entitlement from next April. I am keeping little savings to pay these class 2 contributions it will be too late in April next, as it passes the date for topup. Do I phone again, or will a reply come eventually. In the past I have filled in 2 cf83 forms and no reply, it's noted that are on file, but this has been going on for nearly 3 years?
