Hello,
Do not buy anything from this person. He is a scammer. I have bought a Steam account at g2keys.com. I have changed email, password and added telephone number.
I also added a lot of funds to the account.
After a few weeks my account got locked, proof: https://i.postimg.cc/8CMjFQHN/steamban.png
He recovers the accounts, steals Steam market items and then sells the accounts again.
