Wronged

I ordered 4 items from Romans today and only received 3 Items, but get this the order was totally wrong mxm... I ordered a pizza pie meal, 2 pizza pies and caramel pie. I only got 2 small pizzas, caramel pie and a small pepsi. When i wanted to complain on the app the page where I am to submit proof - the upload button didn't work. So now I sit with wring order but can't complain, soo wrong
