Yes its very true no matter how hard evidence you produce if he charging back directly from CC company the settlement goes to buyer favor instead of seller bcoz of commission , i m saying as per my exp bro as one time i got screwed same way buy a bs customer i given paypal skype chat's , email convs screen shots , my terms and condition too that clearly defines no refund on software bcoz customer already took demo and make sure they works, on top of everything it was virtual good / a software first paypal closed the dispute in favor of me , after a week again its reopened reason bcoz buyer directly charged back via his cc company i talked over phone with paypal like 2-3 times they told me yes they put strong case from my side as they have every evidence they need end result i lost money is refunded to buyer lesson learned from that day i dont take paypal from new customer or unless they have very good members to vouch search google you find several stories like this
