Beyond USELESS customer service

I have been having issues with Telkom since September 2017. I cancelled my LTE contract with Telkom 24 Septemeber 2017. (I am from johannesburg but was visiting family in east london at the time) The consultant (Liz) that helped me in store in East london (Hemingways mall) forgot to attach the cancellation for the LTE to my profile but issued the new contract ADSL line. In October i went to Telkom in Greenstone mall (JHB) to figure out what was going on, only to find out that the cancellation for the LTE was not attached, i then did another cancellation for the LTE contract and the consultant (Victor)attached the whole story of the other consultant not attaching the cancellation. A case was created. During October and Novemeber i was still billed for the LTE line which was switched off at the end of September. I was also billed simultaneously for the ADSL line which was active. My ADSL line was not working (affected by the thunderstorms accoriding to the technican )and i had to send it in to telkom to check out what was wrong. For 2 weeks telkom had my router, thus i had no internet (during end of november/beginning of december) - they still billed me for that entire month and an unnecessary call out fee also charged to my account for December. Given all the issues i have been having with telkom, i cancelled my ADSL contract at the beginning on January) still to date, no one has called to confrim the cancellation and there is no way to contact telkom to enquire about the cancellation. today, 01/02/2018, my bank account was debited with R655 (mobile account apparently). I have stopped all debit orders coming off my account from telkom, i do not understand howw they are able to deduct anythign from my account without my consent. I am extremely frustrated and feel helpless,a s telkom has extremely poor customer support. no one knows what is going on with my account when i call the call centre. i am sent around in circles evrytime i call.
