Online upgrade deal suddenly dissapears along with reference number

Im so over dealing with rude, arrogant and *********** agents. I saw a deal online, app**** for an upgrade and got ref nr and email confirmation stating an agent will call me. I received a missed call (barely rang twice) so i called back. Apparently the ref is not on the system and the deal has been removed from the website. Vadmin agent kendel was very unhelpful and later resorted to ignoring me completely when i asked that she send me her superiors contact details. Numerous calls and not one single person from any dept knows anything about my upgrade. Even after forwarding screenshots etc. Hello peter complaint got wardah to call me promising she will call back later as she had apparently escalated the matter. Its been a week and im still waiting for her call. Is this going to be sorted out or should i rather just take my business elsewhere?? This never seems to end with vodacom! Issue after issue!! I want the upgrade done this weekend or im moving to a provider who actually gives a **** about customer service and honoring deals!!!
