Vodacom Overcharging

I appalled at the dishonest way Vodacom does business with its clients. I haven’t been able to use the SIM card for over a year, and yet I am paying diligently. My contract expires in January 2020, I am not now even able to get a “quote with penalties for early contact cancellation”, because of bill run et al. Also, with the overcharging happening, Vodacom can allow me to cancel my contract today, without any additional payment/penalties. Vodacom has not: 1. Been sending me invoices – or it seems they’ve been sending it to the wrong email address 2. Been honest in deducting the correct amount from my debit order (I have a spreadsheet should anybody be interested) 3. Informed me of any contract “specials” that apparently ended in October 2019, where I could have cancelled my contract already
