Game completely reset itself – LEGO Batman: DC Super Heroes Review

My 7 year old son LOVED this game and worked hard to earn new characters and levels. He even did chores to earn money for in app purchases. The game completely reset itself erasing all of his hard work. I can’t find any help option or contact info, just other reviews mentioning the same problem :(
