Late deliver...Manager not up to standard...Apparently no existent owner

On Friday 21 December 2018 we placed an order with Debonairs Newclare approx. 19:22. Which at that stage they confirmed the order, which was placed on the Debonairs App, and at 20:15 I phoned the store to get an ETA on the delivery, which they confirmed has been prepared and will be delivered in the next 5-10 minutes. 30minutes later I phone again the store to inquire when I can expect the delivery, which again I was told it was just prepared and will be delivered in the next 5-10 minutes...angrily I told the "manager" that it's not acceptable and I would like to know to truth because he told me 30minutes ago that it was prepared and will be delivered in the next 5-10 minutes. At that stage, he put the phone down mid-conversation and I then phoned the Debonairs customer complaint line. The gentleman was fantastic on the phone and got the hold of the manager. Now the problem that I have is that they delivery only at 21:05, which is almost 2 hours late and then still makes me pay for the food. A couple of days later the manager phoned from the store and I told him that I do not want to speak to him because he's not a good manager, actually I said useless seeing that I'm an office manager myself in a customer service driven environment, and asked that the franchise over of that store makes contact with me. The area manager then phones me a couple of days later and takes the store managers side, which I then insisted that the owner makes contact with me. Up until today still, no contact has been made with me. I'm shocked and more than likely not the first customer still has happened to at this specific Debonairs branch.
