Scammed, did a boost from diamond3 55 lp to diamond1. When I was 1 game away from winning the promo to diamond1, he said he's gonna pay in 24 hours, after that he started to ignore me. After looking @ lolking of the account I've boosted, I saw that it was diamond2 20 lp, with already changed password.
Also he pretends to be a lolmeup.com 'manager', will even send you a 'legit' email from "[email protected]", but if you google about lolmeup.com you will see that they don't have a skype account and never hire boosters. That was my bad that I felt for it, but still he's a damn scammer.
