Domino's Pizza

I ordered on line hoping to use a promotional gift card bought through a charitable organization (buy one large pizza get one free). It would not take it on line. Ahhhhh! I found a coupon and received $10 off my order. One pizza had thin crust with 3 toppings which included extra cheese... Where is the cheese let alone the toppings? One pizza was regular crust half cheese half hamburger and again I ordered extra cheese. Again no extra cheese and it had bubbled up while cooking so all the topping had slid to the sides of the bubbles. A cheese pizza should have cheese on it. It was the worse pizza I ever ordered. I do not want a replacement pizza I want my money back of $28!
