I take up to 20 days after paypal remove the chargeback for Joymax to investigate your account and remove the ban.
In other word you need to contact Paypal and make paypal remove the chargeback.
If you activated a premium item... xD
They aren't going to give you your time back, but that the least of your problem.
As for the 20 days, I know it long but it a maximum of 20 days.
As for complaining about all of this being unfair, well it pointless to cry over it.
Won't change anything this is how it work for everyone and there won't be any exception.
Joymax get spammed in the email
pay@silkroadonline.net so the odds of you getting an answer is really low. First get Paypal to remove charge back. The spam joymax until your account is back or you get an answer of a GM telling you to wait an amount of time.
