Offered him a free boost for the account of his girlfriend, successfully boosted her from Bronze 2 to Silver 5 - offered him to boost the account atleast to Silver 3, he accepted.
Wanted me to boost him from Plat1 (54 points) to Diamond 5 then, offered him to pay after the first game. Accidentally lost, boosted him to the promotions, then asked for the payment of 10€. He changed the password of both accounts and refuses to talk to me.
Not recommendable, atleast not till I get an answer from him.
