ROMANS PIZZA MAMELODI CROSSING GETS MY ONLINE ORDER WRONG!

I ordered two large pizza deliveries from Romans pizza Mamelodi Crossing and they sent the wrong flavours. I had ordered one large Hawaiian thick base and one large chicken supreme thin base online. They delivered one large ham sava flava and one large barbecue chicken (single topping). Whats worse is that the delivery guy did not give me my receipt upon delivery. I really did not receive what I paid for which is disappointing, one would expect online orders to be the most accurate but not from Romans pizza clearly
