Vodacom worse than Telkom

Sorry Telkom I misjudged you Vodacom is much much worse than you can hope to be. I've been trying since January 2019 to sort out an overcharge on my account but needless to say without any joy. They will escalate the complaint and then after a month or so of doing nothing resolve and close the case. Should they ***** R50 from each and every customer of theirs they will end up with a very nice bonus every month, seeing that according to them they have 35 million customers. If my deduction is correct as they claim then it means that they can add a 30% increase to a R159 pm x24 add with no repercussion to them.
