Bad Customer Service

When ever a Special being launched and on that date it start no stoke available and for the entire promotion. When manager been approached he Always got an excuses been made with a ? on his face. This is going on now for a year and not only me as a customer experience that. They even refuse to give a Rain cheque on the advertised product. Is this how Pick n Pay bring there customers to the store and \force\" customers to buy normal price merchandise."
