After reading this I also asked for a refund since seller hasnt supplied me with an invite either.
This guy claims to sell me Game Invite in the Dispute opened in PayPal.
Don't buy anything from him, He is a liar and he is fooling PayPal also.
Product for what I paid: MSDN Invite.
He mentioned to PayPal: He sold Game Invite to me.
He is a legit scammer.
