No response to canceling a service

I have since November 2015 been waiting for a technician from Telkom to get back to me regarding a service in my package I want to cancel.<br> On my first call I explained I do not use it as I no longer own a telephone. I have sent e-mails and even left messages on their Facebook page and twitter accounts where I was kept being told someone will get back to me.<br> I got a call from their customer care asking if my matter had been resolved which I responded to \NO\" i was assured someone will contact me by the end of that day. I am still waiting. This is nonsense I am paying for something I do not use and no longer want . Want assistance or service and they could care less but miss one payment on your account and you get a phone within seconds.<br> I request that someone please phone me back as I want this resolved."
