Telkom not cancelling services as requested

I've been trying to cancel some of my services since 6 Sept '19 and till now I'm still being billed. I have to phone every single month and everytime I get promised that this time it'll be sorted. I can't refuse to pay the bill short or not at all else you cut all my services. So I did you a huge favour and cancelled all my services just to get rid of you. Now you can't release my fibre line for me to get another ISP, you DON'T own the fibre line to cling to it, due to some silly excuse and you're costing me a lot of money and business. I have 4 reference numbers already for the fibre cancellation only and each consultant I spoke to gave me different feedback, the last one even saying it will take another 30 days, showing the incompetence of your staff. But if it takes as long cancelling the fibre line with you as it has taken with the other services which was cancelled on the 6th of Sept '19 then I might as well just buy a ****le (from another ISP) and use that till dooms day come. I was a loyal client for years when everybody else left and now I understand why everyone else left, or struggles to get rid of you. You're quick to sign up new clients or sell more products but when it comes to providing that services you sold us you can't deliver. And believe me I have made notes of all the excuses I have been given for all the reference numbers I have been collecting since Sept '19. I had enough now!!!!!!!!!!!!
