paid for stock two weeks ago and haven't received it!!!

On the 25th November 2017 I paid for a DStv explora bundle( installation, decorder, etc) from Game rosebank, I was told that by the following Thursday they would have stock. Due to Black Friday there was a high demand of this particular item. The following Friday I called them, they were still out of stock but would have on Monday. Monday, I called, I was told Thursday they definitely would have. Thursday I called, i was told Friday. Friday I called again, they were receiving stock but were uncertain what they were receiving. There was cer*****y that the DStv would be there the Friday, so I arranged with them for installation to happen on Sunday. I wasn't going to delay the process even further! When i called later the afternoon on Friday, I was told that they have not received the DStv but Saturday they will have. So again, I call on Saturday and I'm told that they will only be receiving sometime next week. They can't confirm a date. Now , I understand that there was a huge demand for this product but surely Game is suppose to have plans in place for such matters. Making people wait for two weeks for paid items is unacceptable. How sure can I be that I will ever receive the goods that I paid for. What makes matters worse is that I have to call the store to find out if the stock has arrived. No one has bothered to contract me and let me know once they receive stock. So now I've paid for items that I do not have and I have to run after you guys. Every year you have speacials for Black Friday, this year you decided to extend the speacial, surely your planning team would know that they need to stock up!!! This will be the last time I purchase from your guys!! You have caused so much inconvenience in my life!!!!!
