@jujisu13, When you change your plan before the end of your plan period, the remaining time on the plan is forfeited. However, if you canged it on the same day, or if the system 'glitched', you should contact the moderators via private message. They might be able to fix things up for you. Gone for the night, but back at 9AM(est).
