Telkom changed my plan without discussing with me on 16 February 2021. They cancelled my fibre line not sure why. Had Fibre for more than three years and always paid my account. Reported problem online ref no ***4. No one phoned me. Requested call back again and was informed that my fibre has been cancelled. They will have to re-instate fibre will get new username and password ref no ***. I called Telkom again today, consultant said back office must load service. Now almost 48 hours no internet
