Poor Management of Orders

I ordered pizza last night, using the app. After waiting for more than an hour, I called the store to find out what was happening with the order. I was then informed that they have not received an order and will thus not process it, despite having received confirmation both on the app and on e-mail. I can supply this as proof. The attitude from the manager, Given, was also poor, accusing me of just causing trouble in order to get free food, which was not the case. I have a small child that was waiting for his food so he could go to bed. This is unacceptable. If apps are not in use, it needs to be deleted from the system. I also feel that Given needs training on engagement with customers.
