Don't take vodacom contracts

Contract ended in October 2021, I was debited November and December. I reversed both payment as it's stipulated that contract ends in October, and nothing was communicated to me that I must call in to cancel and was never advised when I took that contract.

Now I'm being pestered everyday that I owe something outside my contract. Vodacom is pathetic, I need my contact details out of your system, and to anyone considering taking a contract with them goodluck. Don't sign up with this network operator. They're the worse.
