Vodacom full of unprofessionals and *****

On the 10th of November 2022, someone from vodacom called and said she can change my offer of 500MB to 2GB for R18 difference . After our conversation I checked my emails and the migration from 500MB to 2GB was not R18 but was R179. The expiry date was the 24th of November 2022. I called vodacom on the 22nd November 2022 and told them to take me back to the 500MB. To my surprise when I got my statement, had to pay a penalty fee of R575 for cancelation. I've been trying to resolve the matter but nothing is happening. I spoke to the following people and the promised to give a feedback after 3 days: 30/11/2022- Siphiwe Vezi 20/12/2022- Siziphiwe 23/12/2022- Niky Today (28/12/2022) I spoke to Niky again, and she promised to call me back by the end of the day for feedback but I know that won't happen.
