Dishonesty & disappointment

I ordered a pizza from debonairs rosentville at 20h47 online and the store sent me confirmation of my order. After an hour I called the store because I still haven't received my order. I spoke to Melody who told me that the driver would call me any minute now with my order. There after I was contacted by the store to tell me that actually I'm not getting my order because they dont deliver to town after 6pm. I requested to speak to a manager to find out how can this be possible and why was I not informed earlier. Sibongile told me that she doesnt know why and she does not have answers for me. I asked her why was my order accepted in the first place, why was I told that my order was on my way and how do we rectify this? Again no answer further more , in a nonchalant tone she says she cannot rectify this and cannot assist further without considering my overall experience. I'm extremely disappointed with this type of customer service from a huge fast food restaurant.
