Domino's Pizza

I have tried to call and place an order with Domino's at 11:15 and wait and get the store and repeatedly they hang up. I have someone who works at this location and am told they do this to get out early so they do not pay overtime. Why don't they change hours instead of hanging up? Also I have ordered double mushroom pizzas and I can count the number of slices of mushrooms on the pizza. To not have one slice of mushrooms on a piece is unacceptable. I would estimate there are four mushrooms sliced and put on the pizza as double mushroom.
