NOT RECOMMEND. MARK MY WORDS.
I ordered a boost from d2 to d1 and he said that he could end it in one day.
He played 22 games and lost 13, making me demoted to D3: he lost lane in almost every game and his kda is really poor. He claims to be challenger. That's obviously a lie.
DON'T BELIEVE HIM AND STAY AWAY FROM THIS GUY
