KFC app and online services is terrible

I placed an order for my girlfriend using the KFC app. Told her to go with her dad to pick up. When they head over to the restaurant the staff there have no idea of this order. They cannot find it on the system although on the app it shows that the item has be paid for and the money already has been deducted off my account. It's so disappointing that my girlfriend and her family had to go without supper tonight because your ****** app doesn't work and at the same time Ur staff couldn't help at all as well. Instead they kept saying the money hasn't come through. They didn't want to help and mad it seem as if we didn't pay. It's completely uncalled for what a ****** terrible service for a popular restaurant. I'm so terribly sad that my girlfriend had to go home empty handed. It truly breaks my heart that KFC has done this to a good customer.
