Upgrade - Now or Never?

I reached out to three separate Vodacom agents to discuss my contract reaching the end of its life cycle, only to be told that I should wait till February of 2021. I was informed by these individuals (Norwood Mall, Nicolway and the Vodacom Call Centre) that had I taken out a contract towards the latter part of 2020 that I would then be liable for paying two phones. Today (20th Jan 2021), at around 10:30am I receive a call from the "Upgrades" department informing me that I am now sitting at 26 months into the duration of my contract and that I was due for an upgrade last year and that I should have already been able to change my contract and get a new phone. This is deeply concerning as I am not sure why I was misinformed. It does feel like their was deliberate misinformation provided, however I am not sure why that would happen? Considering changing to a new network as I have been a loyal customer of Vodacom for almost ten years now and never defaulted on my contract payments.
