Vodacom are skelems

I called Vodacom to request a contract cancellation quote and the lady who was assisting me said to me that I can actually get a 10 gb of data for free and it will stay the same and it will not affect the duration of the contract and it got free as it won’t affect my bill.She send the quote and the next thing I see on the Vodacom app that a contract that was supposed to end in 5 months is actually upgraded to 2024 and mind you I was paying for a device included in the contract amount now when I dispute this and ask what is going to happen to the device amount because in few months time I would have paid off the device so how are they going to work it out?Well the consultant does not know and all Is for the upgraded contract to be cancelled and settle the old contract
