Vodacom contract cancelations

I learned about a superior fiber option at Vodacom, and since other friends expressed satisfaction with it, I also wanted to make a change. However, when I called to cancel, I was placed on hold for an extended period. Subsequently, they offered me a lower price for the same deal I have had for many years. When I declined this offer, they began to intimidate me with additional costs. I have had my Wi-Fi for much longer than two years and have paid all necessary fees. Following my call, I received a WhatsApp message from Vodacom from the number displayed on the second screen. The representative did not even allow me the opportunity to speak, as it is unacceptable to impose extra charges to extract additional money from customers. This is neither right nor ethical. I am not leaving Vodacom; rather, I am transitioning to a better option for myself. However, it seems that I, as the customer, do not have rights.

I am currently working from home, and with the new box that I am set to receive, there will be a backup battery included. As you, being South African know, this is an essential option. However, the consultant who was "assisting" me stated that I do not require it... indeed, I do not need it.
