Telkom at their best

I have been trying since January 2018 to cancel my landlines as I no longer require it. Every time I contact the help desk, I was told that it would be escalated and even confirmed that the cancelation has been received. I've gone into multiple stores and every time my details are escalated as the stores cannot assist with cancelations. I'm being billed for a service and I'm required to pay for it otherwise my other line will be suspended and will not be able to use it. I'm also trying to get my new line on a wholesale holding block in order to allow me to use a 3rd part internet provider that does not charge extraordinary amounts or throttle lines when a certain amount of data has been used. Which your company is also not assist me with as I'm constantly referred to other numbers or people for assistance. No calls are required, as the cancelation and billing corrections can be done.
