Do you really expect PW to tell you if chargebacks are successful or not? It is not up to PW. It is up to the Paypal dispute process which allows 45 days from the time the transaction occurred.
And yes, I have personally seen large chargebacks of several hundred dollars for virtual currency awarded to the complainant. THis kind of complaint is almost always awarded to the customer. That is why PW always bans accounts that charge back.
You would know this if you have ever had to charge back thru paypal on a product or service. It is nto a matter of law or anything else. It is paypal dispute resolution.
