Hello Buddy, We currently only use Paypal but will be getting more options some time in the future, You could try purchasing VIP from another member of the community for in game money but that's the only other way I could think of. If you are still having issue with Paypal I recommend you contact them and see what they can do to help because we have no access to your Paypal or the account information.
