BEING **** TO TO STOP ME FROM CANCELING

I don't even know where to start anymore. This is my 2nd time on here and I feel like it's just getting worse. Firstly I was never notified about my contract that was due for an upgrade, I decided to cancel my contract instead and in store I was told to cancel it via contacting customer service. 3 times I called to cancel and was told that it has been canceled and I will receive an sms or email confirmation. I never received the cancelation email or sms and Vodacom just kept deducting money on a monthly basis for months. I then decided to rather upgrade as I'm not winning with my cancelation, I was told in store (Vodacom Kolonnade) that I will get the iPhone 14 Pro by Tuesday the following wekk when they receive stock, needless to say it's been months later and I still haven't received a single call from them and they kept deducting money every month. Today I called again to cancel the upgrade and contract entirely, I was then asked if I would rather like a new device in which I rep**** that I've been waiting for the iPhone for months now so I would rather want to cancel. The lady said that they have received stock of the device if I would like to upgrade instead. I then agreed and said that if it's in stock I'll rather take the iPhone 14 Pro and she continued to read the monthly price and assured me that they do have it in stock. She said she'll forward my order confirmation via email which I never received. Later I called again only to be told that the iPhone is not in stock but on back order. WHY WAS I **** TO TO STOP ME FROM CANCELING?? I've been waiting MONTHS and every month I got debit orders for no reason. Now I'm told that they have received stock and that it will be delivered between 3 to 7 working days, only to hear from a different call agent that they do not have any in stock. CANCEL MY CONTRACT
