With membership you're allotted one 2D movie ticket each month, there is an up charge for tickets in any higher resolutions. i.e. XD, 3D, D-Box, or IMAX. Before consulting a manager consider if you bought more tickets then you had memberships to cover, already used your ticket for the month or purchased tickets for a higher resolution than 2D. If you reviewed the terms of your membership and are sure you were overcharged, then certainly contact a manager or the support team.
Check with a manger about it
