Con artist Vodacom agents

Recently a vodacom agent called me telling me with Covid to help vodacom clients they are offering a package with better data deals. He then told me I have been a loyal vodacom customer for May hears so this is a deal special for me. No time in the conversation did he tell me my monthly installment will increase. I have always declined more data offers as I can't afford to pay any more for cellphone expenses. It is the 12th of the month and my data is finish on this new package. I called to cancel and revert back to my original contract and I was advised that it will take 5 working days and they will get back to me after listening to the recording but no one from vodacom has gotten back to me. Instead I get a statement for December showing the R733 and I have always paid R560, this is ****************! Disgusting how can vodacom do this at such a terrible time!
