Dude where's My Pizza ?

I have also had this problem and it seems to be different for every household. With my two most recent households, household 1's child would order pizza and it would never arrive, no matter the type. If the mother ordered it though, it always arrived. With household 2 it is just a young adult and 2 out of 3 pizzas have arrived. With older households I've had various ages try to order and nothing would ever arrive. It really just needs to be fixed.
