Poor service and neverminded attitudes

Friday morning first thing I called vodacom customer care to find out if this was an legitimate deal been advertised and was told yes it was. After numerous attempts finally got through to Vodacom Data Store Baywest, spoke to a salesman by the name of Cody, he assisted me with upgrading process for this deal "Sony Xperia XA1 Ultra plus Sony Xperia XA Ultra for R299 x24 months". I signed and returned all paperwork and provided my consent via email with a copy of my ID to proceed with the upgrade process. He confirmed telephonically that he received and processed all required paperwork and I can collect my phones same day(Friday, 24 November) before 7pm. I was later advised that the store was closing 5pm instead of 7pm and I confirmed with Cody that I will collect on Saturday, 25 November as I would not be able to collect by 5pm, Cody's response was I can collect both the phones on Saturday as the paperwork was signed on Friday 24/11/2017. Today, 25/11/2017 I went to Baywest, Vodacom Data Store asked for Cody and to my surprise was told they don't have stock! They had know idea as to when they would be able to get stock or if they were even able to get stock. Was told that the is running from Friday 24 - Monday 27 November. I asked for management and was poorly greeted by Bruce Chetty, who was No HELP at all. All Bruce could say to me was that he would take disciplinary action against Cody and that they can only get back to me by Monday and by then the offer would be expired! To my knowledge Paperwork/Quotations are valid for 7 days, If Cody knew he could not supply after confirming that both my device's are ready for collection WHY DID HE NOT INFORM ME OR SOURCE THE DEVICE'S FROM ANOTHER STORE. BRUCE himself could not come up with a solution that Cody created instead he came off as been neverminded! I WANT THIS DEAL AS PROMISED TO ME AND AS ADVERTISED IN PICTURE
