Dissappointed

This evening I placed an order online at Debonairs pizza (roykers centre) for the online deal which was 2 pizza's and a free 2ltre cool drink and chose a 2litre Coke. Only for me to receive SMS stating that it could not be processed and to call the store. 2nd SMS stated that my payment will be refunded back to me in 48hours. When I called the store I was passed onto manager, Shameega, who told me my order was cancelled due to them not having any Coke in stock. The manager said she was not around when my order came through. This process is totally unacceptable. No I sit with no pizza's and my money has been taken.
