Bad Customer Service

Bad service Debonairs Vicks Viking. Ordered online, they called me before I leave to ask when can they prepare my order. I advised that they must start as I was leaving my house. I pass by the garage to pour petrol which is next to their store. Then waited in the car for 15 min before I walked in. Only to be told that there's a problem with the system it shows that I ordered 10 pizza's. I look at my order online while they do back and fourth to the manager's office and I do not see what they are talking about. Then before I pay I asked if they have started with my order or not as I am not willing to wait. Then I was told that no they have started but could see that the cashier is lying. She prints out the slip for me and I'm expecting her to give me my pizza then she says please wait 5 more minutes which turned into 20-30 more minutes. I inform the manager that I am not happy with the service. She then blames the cashier and says she made a mistake. The cashier changes the story of 10 pizzas to say when she called me she was informing me that the pizza will only be prepare once I get to the store and pay which is their policy. So I ask her what is the point of ordering online and be given the option that I will pay in store also why there's no such option online to say online orders will only be prepared once you get to the store or maybe if this only applies at their store? dololo.... I get home and open the box the very same boxes which were checked by the manager before she gave them to me and the order is wrong. I had one something meaty and one chili chicken. My order was 1 real deal BBQ bacon and half and half sweet chili and something meaty. Oh and the manage on shift refused blatantly to give me her name. Order number 323 inv:305929
