<human>: Hi Reddit,

First I guess a little backstory. I am 30 years old, and had been playing FFXI since the game launched. Last month, I decided I no longer had interest in playing and wanted to go the route of selling my character. I found a purchaser through a forum online, we discussed the details of the transaction through Skype, and upon receipt of the payment for my character ($800.00) I gave them the account info after removing my credit card from the payment information.

Fast forward to this morning, and I have an email from PayPal in my inbox stating that the seller claims they never received their purchase, which is BS, and that they now need me to contest the $800.00 payment or I will be liable for it. All I wanted to do is get some money back for the years I've invested, and now I have to deal with this mess. Does anyone have any advice regarding what I can do to protect myself?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I sold a game character and now the buyer is trying to screw me out of $800 by abusing PayPal's refund system.
