McDonald's Garden Route mall- no Mcflurry...

This is the 3rd time that I've been to McDonald's garden route mall in George & every time I get there and ask for Mcflurry the "machine is not working" for an item as loved as a basic Oreo Mcflurry that one can only find at McDonald's this is surely unacceptable... What is happening, why is there no Ice cream? We use this as our family outing...
