I contacted the buyer to buy a dota 2 key. he answered me & told me he would sell. everything goes fine & i go downstairs to get my credit card.

Then my girlfriend faint because she has diabetes type 2 and i need to take care of her. i come back 25 min later to see a big wall of text filled with insults & a man saying he revoked his gift.

proof 5 :
he even sent me a screenshot of the steam ticket saying he revoked the gift : http://imageshack.us/photo/my-images/51/ozexs.jpg/

now he wants me to pay 150$ or he will keep the scam report & gets me banned from sythe. i really dont know what to do. i'd prefer to cancel the whole deal but he keeps threatening me on msn & insulting me.

he keeps blackmailing me and i dont know what to do. if i could , i'd cancel the trade but he seems to refuse & wants me banned.

i'd like to discuss this further with mods if i could to clarify the situation.

edit : now he keeps telling me its too late to cancel the trade. either i pay him 150$ or i get banned. so this is the problem. he can still revoke his gift but i have to pay him 150$ to not get banned from sythe?

legit as fuck.

2nd edit : i believe i understood his scam. he sells the gift , make the user pay. then he revoke the gift via his support thing and proceed to resell it over and over to make money out of it by scamming people.

 

You're banned.
