I bought 2 Tripple Decker Pizzas

I bought 2 Tripple Decker Pizzas. 1 Something Meat which had less meat and sauces and a Chcken Flavour. Crust is burned and dry and has a aftertaste bitterness. The pizza itself was hard as it was long done and just warmed up and sold. This is totally unacceptable and something needs to change
