Abhorrable Customer Service

Absolutely terrible service. Ordered food from the app and didn't get my order which I understood is not KFC's fault. My problem was how I was addressed regarding this. Called the customer service and had to wait for their call back, which I didn't get, called KFC Arcadia to find out what's happening only for them to give me horrible attitude where one man in particular asked me how can I ordered food at that time and when I asked him to not speak to me like that and not say that, he proceeded to give me an attitude. Told me that I can come get the food, got there only to receive cold food and he wasn't wearing a name tag told me his name was Theto. Firstly, if we're not supposed to order at 8, don't make that option available. Secondly, customer service is a must at all times. Thirdly, the service center shouldn't just leave customer complaints hanging. I'm absolutely disappointed especially considering it's still new.
