Panera Bread review: customer service/employee

I placed an order for delivery and upon checking out I noticed there was no delivery charge so I called the store. I explained the issue to the employee who put me on hold and then came back to say the store no longer offers deliveries after 3pm. I asked that the order be canceled. She said ok but I insisted on waiting for confirmation of the cancellation. She put me on hold again and came back to the phone with a nasty attitude and argued that I didn't order delivery. I had to ask for the manager repeatedly. The manager explained that the girl was confused which is fine but I do not appreciate the unprofessionalism and having to argue with someone who's intellect is clearly questionable. I have had multiple issues with delivery at this location with the same employee and her attitude however in person service has always been great with everyone else. This is absolutely ridiculous!
