Lack of service bluff nandos chicken manager and driver ride.

I called through at 10:56am for delivery of a hot pot, was told the order will take 25 mins to reach me, I called back at 12h00 to check why the huge delay as my lunchtime will be over, I called n the manager reassured me the delivery will be there anytime, at 12 h30 no delivery still, quiet irrate at no follow up by manager, I told him if your driver arrives now I will not accept the order as I must now make alternate arrangements to get lunch and my lunch break being over, he told me to plz accept the delivery n not to pay as they are at fault n to ask the driver to call him to confirm this, driver arrives at 12h45 and tells me "you cannot get food for free" and drives off.. I call the store manager bongani and tell him of the behavior and poor service I received and basically nothing will be done... I called 8 times due to poor service checking n being promised my order on its way.
