Depending on the situation, if you charge the wrong QQ account with qb, you can choose to charge the wrong qb account into another account to buy the League of Legends point roll, note that this is to change the qb into a point roll into another account, rather than giving qb ah.
If you have changed the qb into a point roll, there is no way, the point roll can not be given, but you can choose to buy the props you want in the LOL client or Tao Poly City to give you the number you originally wanted to buy something.
