Very Much Disappointed

I am very disappointed with vodacom. My contract was ending in July 2023, I stopped using the sim card in July 2023 knowing that I wont have data loaded anymore, vodacom stopped debiting my account and the sim card was blocked in July. So today I switched on the modem wanting to recharge and use only to find out that there is data on the sim card and only then an sms for payment came through my phone and a phone call came in from a very rude consultant. Now vodacom wants me to pay premiums for Aug, Sep, Oct and November, hey my contract was only for 24 months and not more therefore I am liable to pay for June and July that is what I signed up for and the sim has been inactive for all the other months they want me to pay for, n one ever called, sms's or emailed until I activated the sim this morning, this vodacom is a **** really...
