Guy is cheating me on ebay?

I paid him $6.00 for an item. He says he will not give it to me unless i pay him or he'll start an unpaid item case I SENT HIM A PHOTO PROVING I PAID HIM, he doesn't believe me. I'm still new on ebay so I'm not sure what to do. I want something to make him give me a FULL refund or give me the item RIGHT NOW. They are the email and pass for an account (Minecraft) so he can send them to my e-mail please help me.

Added (1). I have told him to talk with me quietly to resolve this. He says he hasn't received ANY payment from paypal, does paypal take time to deliver the transaction?

Log into your own Paypal account (NOT by using some criminals 'phishing' link in an email. NEVER EVER click on links in eMails.)

In you can't see the 'transaction' in PayPal then you didn't pay him. Change your password IMMEDIATELY…

If you can't 'get in', then it's too late, your PP acco8unt has been 'phished' and some-one will be emptying all your linked cards / bank accounts right now. Notify Paypal and your Bank / credit card co. Immediately.

Is he a new seller? If so he is subject to the 21 day hold on his money at PayPal.

By the way, selling most online accounts is forbidden. You can get ripped off so easily this way.

He can open a case for Unpaid Item and you have proof it was sent. If you used Paypal it will be in your transaction history. Something may be wrong with your account or with his Paypal email address. If he opens Unpaid case, Ebay will ask you to prove you paid and upload the proof. Buyers always win cases. You can call Ebay and find out what the problem may be. Last thought, if he is a new seller, Paypal withholds all funds for 21 days.
