He trusted me because i am not a new member and i have already had some deals here. Sorry mod i cannot agree on sending him the money back, i know him better than what you do, so please don't ask me to return the money back to him. I am ready to refund it to you but i cannot transfer him back directly for security reasons only. He has blamed me for things that i have got nothing to do with so i cannot trust him at all, i am sorry.
BTW, as for the mark on the motherboard, it is actually nothing, it was just a sweat mark that was there when i pictured the motherboard back in February before posting it here. But before sending the motherboard to the buyer he asked for a clear picture and i already forwarded it 15 days back, so there is nothing on the motherboard.
his cabinet and psu are also ready to be shipped back.
and there was one more thing that i doubt, i think the buyer might have already registered the motherboard in his name, he called asus india and also verified the warranty online. So if he has already registered the motherboard in his name or maybe someone else, then i wont be able to accept the motherboard back.
