It is great that they do take out Pizza, however, it would be helpful if when they say collect in 20 minutes, and you do collect in 20 minutes that the pizza have not been sitting around for most of that time. Service should be helpful not confrontational. Pizzas should be hot not stone cold, quality of pizza poor and one of the orders was wrong.
So - to be constructive. Please train your staff to listen to the order, train your staff in the pleasantries of customer service. Train you chefs to cook with care. A shame that the experience was poor. Hope they can find ways to improve.
