What happened::So here is the little story. I have contacted this guy @awsactivate to buy aws 5$ credit accounts
After 2-3 days of being hesitant to go first. i have decided to take escrow. ( He agreed because he knows the loophole, escrow services are costly , he pointed me to a guy @SebastianJu He charges 150$ itself ) So, dealing with direct is good choice for any one here.
Now that i have sent the 200$ to him.. Voila... Chats cleared & Blocked me right away.
One suggestion for Bitcointalk admins and escrow services : Please lower your fees or these will happen every day. ( Not a good sign for a good community )
I know i am not getting the money back.. but atleast someone else should not lose money.
One more thing. Negative reviews wont help , nor suspending his account. ( he will create again and scam others ) . Better to fix the root cause and build a better and cheap escrow service.
