Called in advance before having my family drive over to this location to get the cotton candy blizzard. I called a hour before my family got there and confirmed they had the cotton candy flavor. My family gets there to get the blizzards and now they don't have the blizzards. They gave us 30% off but acted like it wasn't their fault and that we didn't really call today: If you are out of a flavor you should give a customer a heads up since other locations don't have it. 3rd Dairy Queen in this town to provide poor customer service.
