Frustrated

I tired of the experiences I've encountered with Romans pizza in evaton mall. I ordered pizza pie pepperoni flavour and I was given the chicken BBQ flavor and this is happening for the 2nd time. The last time I was given some flavor that I don't even know. Don't the staff check the orders though? This happened on Saturday round about 11:30, unfortunately I only checked my order when I got home as I was in a hurry... I don't think I'll ever buy anything from there again, if it's not bad service it's wrong orders.
