《Ice Land》If I would like to continue after completing a single private lesson, can I add money to my balance to purchase a 4-class course?

If you have purchased and completed a single private class and would like to change to a 4-class course, please pay the difference for a 4-class course within the same day. If this is not done within the same day, you will not be allowed to just simply pay the difference between the 2 course types in the future (i.e. the class may not be used to receive a discount when purchasing a 4-class course).
