Denied.
This guy is using a coloured nickname, so "Kongo" is not right.
If you want to decipher it upload the replay (http://replay.garena.com/) and his real nick will appear.
Besides you can on the one hand, look in the room if he is still there and note his nick or, one the other hand ask the host, because he can see the leaver's correct nickname when he joins and leaves.
