Appalled with service [KFC-Mr D]

I ordered KFC through Mr D , first they only delivered the drinks and the second part of the order came separately and 2 items that i paid for didn't come with the meal. There's 2 things that went wrong, i am totally disgusted at the level of service i received as i am a frequent user of Mr D and KFC. This made me uninstall the app and not want to order KFC again. I encourage everyone to not use the app as there's no trust and you end up losing money.
