I recently bought the Prison Escape skin pack for Minecraft Pocket Edition, and it worked as intended for a day. However, the next day, all the skins in that pack were suddenly locked for me, even though I paid full price for it. I also bought the Cute Skin Pack yesterday, and it worked for about an hour, and then the skins were all immediately locked. Is there any way to get these skin packs that I paid for back, or is my money gone for good?

Thanks in advance.
