Twinpack not two but one

My daughter has a sweat problem and the only roll on that actually HP's her is Mitchum for men.We recently bought a twin pack from take alot and the one roll on was actually empty.Like it had literally nothing inside.This really inconvienced me as i normally buy the twin oack as it saves me money.Pkease look into this matter as i usually order from takealot and this is a first.
