Bad attitude/ false advertising

I logged a call regarding the tablet that were advertised at Ackermans for 599.00. Gillian from Head office phoned me and informed me that "sorry" items were sold out. I said to her that we contacted 4 different stores and they all told us the same story they are awaiting stock or in the case of Springs they were sold out but awaiting more stock and will contact us as soon as stock will come in. Then Gillian said well stores were supposed to remove the promotional ticketing from their windows and that the stores " moet nou maar vir jul een gee". I told her that the guy in Brakpan even took my wife's number and said they have not received any stock but as soon as they get he will contact us. Gillian admitted that some stores did not get stock at all . According to your web site it was available in all stores. I told Gillian that I do t care but she will find me a tablet at that price before Thursday. She then very rudely and unprofessionally said " ja dis reg ek maak so tot siens " and dropped the phone. I just received a call from Thabo at the Eastgate branch to say that stores received communication that stores will not be receiving stock on the advertised product as it has been discontinued! How can you put an item on promotion knowing that it is bring discontinued??? Where is the values of Ackermans? How misleading is this to customers? I will go public with this as others were listening in on the conversation I had with Thabo.
