bug:zp instead of gp

hi guys.i bought a 40k gp esn code in playspan today.after i used it i had no gp but 20k zp were added to my account.i dont want to get banned,although it isnt my fault,because i didnt knew about that so i didnt used the zp.if ist a bannable reason please remove the zp and add the gp,otherwise im more happy with 20k zp than 40k gp^^
