Vodacom is *****ing my money

Around July 2023 I called Vodacom to cancel my contract number ***. The agent convinced me to remain on the same package at a reduced subscription. She said by doing that they will reduce the price on my main package. I am not using ***. Last month I decided to use it and went to use it and requested a new SIM card, but Vodacom in JBay advised me it is no longer a data contract but a Flexi 75. It was a data contract beforehand expected it still to be one as that it what was agreed on.I then formally requested the recording and they promised to give it to me but never did.I also requested Vodacom to reverse all the changes as it was not what I requested and put me in the same position as I was before the changes. I then noticed on my latest statement and bit order they are now charging me around R 2000 more than it was before the changes. That is not acceptable. I called in this morning and spoke to Shoab Mohammed who promised me a manager would call me back in 15 minutes, but it is now almost 2 hours later and no one has bothered to call me.
