Misrepresented packages and frustrating customer service

Absolutely frustrating experience since my last upgrade. The package was not explained to me, then a bunch of extra VAS services added on without consent (which took numerous calls to get removed) and now lastly I can’t top up data from the app or USSD (have to buy physical airtime and convert). In order to correct my package, Vodacom is saying I will have to pay more per month. At one point I finally got a lovely, helpful person (Sam, team lead) would raised a ticket and promised to find out what can be done. Someone else then called back, saying the correction (to an open package instead of a top up) will override the discounts given to me at time of upgrade and I will then pay more. When I said this is not acceptable (given they convinced me to take the upgrade on the Package components on minutes and data, plus cost), she said she’d escalate the matter - but instead closed the ticket!!
