[Luxor]

can you guys help me with this, so i became admin of this page about 3 weeks ago and i dont want to be on this page anymore i asked main admin to remove me but he won't, and he won't text me back so i tried to find how to remove myself off admin but i cant do it, and if that is impossible to remove myself how do i report it to facebook ? or what do i do ? because they are advertising this page and it costs money, example: if i dont put my visa card or whatever it wont take my money right ? because im worried i dont want to waste my money on this page and i afraid it will take my money cause i have already used my visa card on 1 game on facebook. so help me please
