Highly disgusted

On Sunday I went and ordered 2 pizzas, eventually when they were ready the 1 order was wrong - my sister who hates onions clearly asked for a tangy Russian with no onion and I ordered a hot one with extra basting as this pizza is very dry.. nevertheless so she got her pizza WITH onion and i received a pizza with only the inner with toppings. It must've been a good 10 cm on the outside with no topping or no sauce. So I basically paid for 1/2 a pizza. She complained about the onions and she got such a look from the staff member that i didnt even bother to complain. I mentioned to her that this is not acceptable, if i wanted half a pizza I wouldve ordered one. I dont know if they were just busy or lazy, but this is not acceptable. They should start listening to orders and execute it properly - and the guy who makes the pizzas should learn how to cover the pizza properly not just the inside part of it. If I could, i wouldve attached a photo here to show you how bad it actually looks!
