Dominos Pizza — I pizza undercooked and one burnt on edges

I ordered 2 pizzas from the mix and match for $6.99 each and also a sandwich ( no problem with sandwich). I picked up the order from store 1537. We have ordered from this Dominos for years and this is the first problem we have had. I ordered a sausage and mushroom ( hardly any toppings on the pizza and it was undercooked. I could not even pull apart slices. My husband had a pepperoni and salami pizza that was burnt around the edges. I was very hungry and could not eat but one slice of under cooked pizza. I have ordered many things off the menu and this is the first time as I stated that the food was a real disappointment. We threw away our order and I heated up left overs for our dinner. A refund or coupon for the 2 12pizzas since they were not edible.
