Telkom-nightmare to cancel services

In October 2019 i connected to Fibre and it was not necessary to use the Telkom ADSL service anymore, I decided to keep just the voice and cancel the ADSL part only which has been a nightmare as it has been impossible to do this. You cannot do this with the call centre as they refuse and you have to do it online which i did. Despite receiving emails and telephonic call and sms s that the cancellation was done, this was never the case, the reference was ***9. Apparently they only cancelled the internet but not the Broadband part which i am still paying for. Every time i call in they confirm that it has been sent to the I T department and will cancel within an hour. This was at End December 2019. To my shock i discovered yesterday that it it still not done. And the call centre agent **** and confirmed that the Broadband is now off. I have never dealt with such incompetence in any other company
