I played half of the boost with decent KDA and good w/l and after halfway of the boost he wants refund because of his grandmom got diagnosed with cancer and he needs medicine that costs 145$ and he only had 115$. I refused to refund since he ordered it and i was nearly finished.
EDIT 2: Now he writes on my thread with 3 of his accounts and proof on skype that he has 3 same accounts on same IP.( Multiaccounter)
EDIT 3: The positive rep he has gotten is from 3 of his accounts so what i know maybe more than half of his positive is from friends/himself.
