In Dec 23 I was deemed eligable to pay class 2 voluntary contributions I subsequently paid by sterling cheque from abroad to cover 17 yrs of gaps.I contacted hmrc and they confirmed receipt of payment.when I checked my account I have been credit with only one year(23-24) even though I provided a cover letter explaining the years I wanted to fill 2006 to 2024 will this problem be resolved? or will I have to phone again?very difficult to get through and a long wait before anybody answers . I am aware how busy you are but my time is important to me too! All seems abit of a mess
