Telkom Fiber

I am moving to a different address on 30 November. I have contacted Telkom to assist me in moving my Fiber line. Unfortunately they do not have coverage in the new area. I then asked to cancel my fiber line, after being pushed from pillar to post i eventually got through to a consultant that send me a link to cancel my services. After capturing all my details i got a message on the same page that my account can not be found. I then tried registering on the Telkom App but that also did not work. I called back and this time i was told that this is a third party line through vuma even though all my billing has been through Telkom for the past three years. I need assistance t cancel this line as i refuse to pay for the month of December because of the incompetence of the Telkom staff.
