Upselling under false pretence!

Someone from Vodacom's rewards programme contacted me telling me I should migrate to a new package where I would not be charged for the migration and I will NOT be paying anything additional on my contract. I asked the person over and over again to say "Will I pay anything extra on my contract?" and I was repeatedly told I would not be paying any additional funds. This all happened on the 12th of July 2023.

I get my statement (Early August 2023) and guess what, I have been charged. I then call Vodacom customer care requesting for the recording of the call and I am told I could not get it because there has to be an investigation first before I can get it - LIKE INVESTIGATE IT THEN. Just because I had asked to be taken back to my original package, I would not be able to get the call recording.

Like What is so difficult with just sending me the call recording and also listening to the lies I was told. In a nutshell, I would say I was up-sold services under false pretence and I will keep complaining until that call has been made available to me. THIS IS NOT COOL. Don't be lying when upselling stuff. Really unfair! Please just send me the call recordings.
