Silver IV to Gold IV
Got the
Got the boost right before the End of season, which made it much harder for the booster because of smurfs and other boosters. Took couple more days then expected, but finished right in time before season ended, and even granted a free extra win, just be patient guys. Good communication between booster and costumer. Recomended :)
