Was suppose to boost him g5 > p5 for 75 euros since he said his LP gain is 17 - 20 LP / win. I won a game on red side (red side gets more LP than blue) and I got 14 LP. We agreed to change the price to 100 euros for the boost due to the low LP gain, he said that he would send the money and after 5 minutes he changed his mind and said he's going with another booster.
Also, he had low priority queue so I had to wait 10 minutes because of that
