Query: They only sent half the order

Just received the cubes and have no idea if they will work or not. However, Hurt only sent 36 cubes and not the 72 specified. Even after I replied to their confirmation email (which listed 36), informing them of the error and even included a link to this website. Still, I give the produce 2 stars in the hope that the cubes are not as bad as their customer service
