Paypal question

[BlueLights]

Hello, a quick question for those more experienced with PayPal:
Found a seller for my game account this week, he will pay trough paypal. Now, i don't have a credit card that's enabled for internet pay, and i am skeptic of attaching my credit card to my paypal account, because the buyer might decide to take back the money back, and i don't want to pay off of my credit card. But, and here comes the question, i know a trusted website that sells a game key i want for that money, without needing a registered paypal, only a one-time phone verification, and it's all good.
The problem is, if the buyer does decide to take his money back, after i buy the game code and obviously verified my account on that site with my phone address, what exactly happens and can it be troublesome.
The process being: I get the money on the unverified paypal -> I give the account details -> I in the next hour or so I pay from paypal and verify my account on that site with a phone call -> Gamecode comes trough e-mail. If the buyer decides to solicit the money back after i payed for the cd-key, what happens.

I wouldnt recommend doing any business on a unverified paypal.

Yes, but if i did transfer the money, can the money be taken away from the transfer destination or does it cause any issues to them?

or you will loose in the end, trust me.
