Vodacom contract renewal skills

My Vodacom contract ends in a few weeks. I received a call from a Vodacom representative (An Indian lady, ***, 11:31 am, 27 March 2025) about renewing my contract. She said I received a monthly invoice from Vodacom, which I do not. She said the starting payment of my contract was R404, 60, which is wrong, it was R349. As to the problems with my router she did not answer, and the conversation became quite unpleasant, and somewhere along the line she draws the illogical conclusion, "So, you want to cancel the contract?" When I stated I would do my research before considering Vodacom again her remonstrations were unacceptable to me, and the call ended. I was still wanting to ask about the annual 13% increase on my bill. Vodacom Management, you have the details, listen to the call, let me know if you find the content and culture of the call acceptable in a competitive market place.
