Getting billed for fibre not working for months now!!!

I have upgraded my adsl to fibre in January 2020. Since inception the fibre is not working. I spend more then 10 hours on the helpline and no one has fix the problem but telkom has billed me for the fibre. How can the bill me if it has never worked? I just want the fibre in working condition, its really frustrating. As i also got a letter of suspension of service, the want to suspend my adsl line, but i paid it up to date, i didnt pay the fibre portion. I am fed up and dont know who to talk anymore. I can afford to be blacklisted as i will loose my job, but how can i pay something that doesnt exist. I am in tears, frustrated, furious and just want my flippen fibre to work! PLEASE HELP. I anyone can help me where to submit a complain so that they can actually help me, it would be appreciated. I am considering the ombudsman as well.
