GAME Boulders, Items not delivered and charged!!!

I purchased an appliance for 5K from Game Boulders, paid a delivery fee and asked that they deliver in a weeks time. I gave them specifics of which day and was told that theres enough time and they will deliver on the day, and i shouldnt worry. I called them twice in the week and on the day of delivery to confirm and was told that they will definitely deliver. I called the store now and was told that the driver is in Germiston and too far to get to Midrand to deliver now. I spoke to Susan the floor manager as I was told that the store manager is not in the store and left for the day, and still nothing. Please tell me how this is fair that you get charged a delivery fee and afford them a week to plan this yet still cant get it right?
