An upgrade that is forced down my throat.

On the 24th of May 2024 I phoned Vodacom To cancel my Reuter contract as I had network issues and I felt like I was paying for free, I was convinced by the consultant that they will Offer me a better package, I asked him to send everything on email, I received the email then I realized that I was mislead. I phoned Vodacom On Monday to reverse the transaction as I was told that I have 14 days to cancel. I was told I have to wait for the devise as it was dispatched already. Sky net came on the 27th I rejected the device. Since then the device haven't reached Vodacom warehouse, I am being told they wont cancel the upgrade until they receive the device.it took them 1 day to deliver but more than a week to receive it back. I need this cancelled ASAP.
