I contacted BattleBoost about their legend boost for Hearthstone. I was diamond 5 and couldn't get over the hump. The person on the chat was able to answer every question and was so helpful! Once I ordered the booster was able to start right away and went on an insane run and got me legend within a few hours! I will absolutely be using their services again if I ever need! They were helpful, literally, throughout the entire process!!
