Complete disrespect of customers!

Placed an ASAP order for a product that was on special. The incorrect product was delivered. Reported the issue and Pick n Pay. Was promised a resolution and feedback before the end of the day. No one made contact to called again the next day. Now with different stories that i will not be able to get the product at the special price anymore. Only once I reminded the agent about the Consumer Protection act, was I Eventually connected with a manager called Kaylyn (not sure of the spelling). I rephrased the consumer protection act to her, and she then finally comitted to resolve the issue (time was about 16:50) and then call me back by 17:00. At 17:10 still no feedback. I then phoned again and asked to be connected to the manager, only to be told she is taking a break. WOW !?!?!? In what universe is this acceptable customer service ?
