Hungry Howie's Pizza

first off they got my order wrong, i order a small deep dish with pepperoni and they put pineapple instead. Then they put their garlic butter on first before they bake it which made the whole pizza taste burnt. When i called them and told what happen they said thats how they make their pizza. Every other hungry howies i've been to puts their garlic butter on after. So how was i to know to request the butter on last. They wouldn't make me a new pizza or fix the one they messed up. I would have to buy a whole new one. I'm very unsatisfied....
