Dear RF Online and ArchLord players,
Due to continued fraudulent use of Paypal accounts in relation to micro-transactions, we are left with no alternative but to withdraw Paypal as a payment option for micro-transactions (cash shop credit purchases) until further notice.
Any customers using Paypal for micro-transaction payments will be required to change to one of the alternative payment solutions listed below if they wish to make future purchases.
Click and Buy
Worldpay
Whilst we appreciate this will be inconvenient for some of our players, this action is required to ensure the integrity and future of our free 2 play MMOs.
Paypal will continue to be a valid payment option for our subscription games.
