Vodacom review: deals

Good day i would like to complain. we went to Vodacom Chatz N1 City in Western Cape. we saw the new Christmas deal book on the 9th December and we needed to up grade my wife's current contract and we wanted to get the PS4 which was in the magazine for my 10 year old for Xmas. On the 12th December we returned to the shop did all the paper work for the cell upgrade as well for the PS4. we were told that they will place order for both and let us know when we can collect. A week later when we returned to the shop we were told that they have the cell but not PS4 and the manager Nazeem spoke to the buyer and was told that it might only come about the 28th of December. we in turned said okay we will wait. the beginning of January we went back to the shop and they said that they will try and have by the end of January and said okay cause then we can give it to by 10 year old for his birthday in February. At the end of January when we went to the shop the sales man and the manager could not even look us in the eye and we then cancelled the PS4 as we needed to get the cell. i am extremely disappointed in Vodacom as i am in retail and the customers industry for over 25 years. we walked in 5 days after the December deal magazine was out and you had no stock. this tells me that you put a product in a deal book and you knew you had know stock. This is bad planning or a way to get people to sign up and get feet through the door. I know from sales experience that companies first test the waters to see how the response is before they order stock that hey can't return. i would like to get a response that makes sense and that there is a way of you assisting me in getting this item as i was a list at Vodacom Canal Walk and had no contact from them.
