THEY DO NOT HONOR THE ORDER
I know for a fact that this service permits boosters to deviate from your order. They will combine orders and allow the booster to casually ignore your selected role to help another order or their friends they duo with ON YOUR ACCOUNT. They'll try to say it was autofill, but then when you give them the proof off of op.gg they just shrug it off and tell you that you are S.O.L.
