Incorrect Order/Bad Service

I placed an order for our company 11 pizzas to be exact,we were going to collect so we placed an order over the phone ,which firstly the lady taking the order was confused as hell and i had to repeat my order numerous times.When we fetched the order we did not get what we ordered,it was in a mess nobody knew which was there correct pizzas,which was unacceptable.I did call the store manager who was very unhelpful and to be honest he couldnt care less!!!
