You can make chargeback within forty-five days of the transaction. Log into your paypal account and click on the
"Resolution Center" link and then click on the
"Report a Problem" link. You will have two options:
Item dispute: I did not receive an item I purchased or the item I received is significantly not as described.
Unauthorized transaction: I did not authorize a recent transaction.

Choose whichever you want and fill in the form. I suggest you the first one because if you choose the second one they may block your paypal account in order to prevent more unauthorized transactions. I suggest click on the "Learn more about opening a dispute" link and read everything there for getting the details of this process. Because you should close the dispute (which you wont) or escalate to a claim within 20 days of opening the dispute.
Paypal automatically closes disputes after 20 days and a closed dispute cannot be reopened or escalated to a PayPal claim.So i suggest you to escalate to a claim right after this process if it is possible.
BTW i have never made a Paypal chargeback. I just logged into my Paypal account and made a search about it for you and also for me incase i may need it in the future.
Ogh I hope you are not thinking of making JM to ban your main account in order to quit the game! ROFL
