Service delivery abyss

Placed an order at 18:47 with Steers "Burgersfort Mall" for collection and I get told the order will be ready in 15min and receive an sms confirming the order. 19:15 I drive to the above mentioned location to find the steers has moved to another location. On arrival I get handed a wrong order and when queried I am told the order I am looking for was not received. Only to find that my order has been sitting on the receiver from "head office call center" for over 40min and I must still wait for it to be prepared. I further get advised to change the order as my initial order will lapse past the time that the store operates within. Why offer a convenience based service to customers to only waste their resource(Airtime, petrol, moreover TIME) and defeat its purpose. Deeply disappointed!!
