It doesn’t sound right. Look at the guide that LJ posted and see how it works out as it may be an administrative error? Just go through that process guide and see if the figures are right. If they are wrong then try contacting DBS through a JPA iSupport request, or try the Fg Branch Advisors as they are hooked into the Pay and Pension teams. They also have a virtual Crew Room on Defence Connect so you can try dropping them a line before the end of the Christmas block leave period.
