Untraceable order lost and found

We ordered pizza online last night. When tracking/tracing it on the online menu button, it said untraceable. At first it said its being prepared in the kitchen. Then it said untraceable, the order number was there. After 40 minutes we decided to call the branch. Only to be told that there is no such order. The lady said that she is not able to trace it using the number either. She insisted that e had ordered from another branch, even though I continuously told her it was theitlr Branch. She said she would put my call through to that other office or branch. My aime for the call is consuming all this time. I waited and waited. Till the call cut itself off. I then called once again. This same lady, this time said, oh you are so and so, calling me by name, and said that my order is on its way. Unbelievable. We awaited another 20 minutes got a all from the driver and got served a cold pizza. Very dissatisfied.
