Beware with this user. I sent the account first and he changed the details
After that he said there's some problem with his BTC wallet, and can't send me the payment (which I don't buy it)
I waited for 3 days, and when I tried to reach him there's no respond from him, he also blocked me on steam.
As all of his account is new (BTT, Twitter, etc), and he is not responding, which seems suspicious to me
So I locked the steam account and asked for support's help to retrieve the account back
And he showed up immediately after I locked the account

Still, though I made very clear that I will unlock the account as soon as received his payment
He refuse to pay and threat to leave me a negative feedback if I don't unlock for him first
Of course I refused, I have nothing to hide and I'm not the one who broke the agreement
I'm posting here to warn other members to deal with this guy with cautious
I doubt he was planning to pay me at first place.
I will provide chat log if needed.
