DEBIT ORDER DATE CHANGE PROBLEM

FOR TWO DAYS I HAVE BEEN TRYING TO CHANGE MY DEBIT ORDER DATE. YOUR FIRST CONCULTANT TOLD ME THAT I NEED TO CONTACT VITALITY IN ORDER TO CHANGE THE DEBIT ORDER DATE. I CONTACTED VITALITY AND THEY TELL ME TO CONTACT VIRGIN ACTIVE BECUASE THE ACCOUNT IS WITH THEM, THEY CANNOT CHANGE IT. NOW WHEN I CALL VIRGIN ACTIVE AGAIN I AM BEING TOLD THAT THE DEBIT ORDER CANNOT BE CHANGED, BECUASE IT IS SET THAT WAY FOR EVERYONE. SO ALL PEOPLE WHO BELONG TO THE VIRGIN ACTIVE GYM GET DEBITED ON THE 1ST OF THE MONTH, WHICH IS NONSENSE.
