Online upgrade lies

On the 23/11 I phoned in to cancel my one contract, but the consultant eventually convinced me to rather do an upgrade. Quotation has been processed ***. Use the order number ***. I decided on a Samsung 43" smart tv and 600GB home LTE data for around R386 (can't remember the exact amount). I asked the consultant at least 5 times if he is sure that there is stock of the tv and he confirmed each time that there is and said it is a new deal, so there is definately stock. Just before we ended the call I asked again if he is sure there is stock and he confirmed yes. As the call was ended I received an sms to confirm the updgrade but informing me that there is no stock and I will be contacted when stock becomes available. That upset me and I sent a message on your FB page to which I received a reply "upon stock availability, you will be informed". I phoned the upgrades department again to which they confirmed after checking on the system that stock will arrive on Tuesday the 30/11. Yesterday I phoned again to find out if the stock arrived and when I will get my tv. To which the consultant rep**** that it does not state anywhere on the system when the stock will be received, so I was **** to AGAIN. He told me I can go to an actual store and see if they can help me with a tv deal, but I won't get it at the same price as the deal I originally selected. He said he will phone me again today to see if he can load a deal with the tv's that you do have in stock, but this obviously will not be at the original price I agreed to. This is totally unacceptable. I already told my parents that I am giving this to them as a gift for their anniversary this Sunday, but clearly this is not going to happen. I expect a manager to phone me to sort this mess up from your side out and keep to the agreement which was entered into telephonically whereby stock was confirmed.
