HELP!! Double subscription for diamond in chess

I have a an account that I've been using for a few months now, enjoyed playing so i applied for the monthly diamond promo and used it for a few months. A promo came up for a yearly subscription which would be half the price, so i took the opportunity and bought that. Unknowingly i actually still had the monthly subscription active. So now i've been charged yesterday for the monthly subscription while my yearly subscription is still active. What do i do?? Would really appreciate help..
