Misrepresentation and poor service

On the 22 August 2022,a rep from Vodacom 031 number called me, telling me about migration on my contract number, #an additional 2g and 100mnts at an additional fee of R38pm starting from the 1st September. The following day I called Vodacom customer to check if the rep is for Vodacom, to what they confirmed it is. But he **** to me as the migration was for more than R200. I requested them to cancel it and requested proof, I was told it is to be escalated, assuring me that it will definetly be cancelled. On the 23rd August, a consultant called me from Vodacom, confirming that it has been canceled To my surprise, on the 1st Sept, no cancelation and migration has been implemented. I sent an email to Vodacom customer care at 3h00 as I could not wait for the morning. I called cancelation dept to do what I requested with immediate effect as I don't wanna see any extra debit amount from my bank account. As always, I was promised that it will be done and they will communicate. To date nothing happened. Please I need this to be resolved and return to my original deal. This is a serious misrepresentation, misinformation and taking customers for a ride.
