Cybersmart and Vumatel created a ********** account, now they refuse to cancel and are forcing me to pay for a service I did not choose nor utilise

Vumatel in partnership with Cybersmart have **********ly created a Cybersmart 10Mbs fibre account without my consent. I requested Cybersmart to cancel the service immediately on Tuesday, 27 October 2020 because I did not request for the product. It was the Vumatel consultant who ordered a Cybersmart package when I explicitly ordered a package with another service provider. Instead of investigating the matter and treating clients fairly, they insist on a 30-day cancellation period with costs. However, I did not accept the delivery of the router nor have utilised their service.
