Complete lack of communication with paying client

I have been attempting to make contact with Telkom for 2 months now. I was moving from my place of residence but had not been able to secure a property due to the high demand for rentals in the area<br> <br> After failed hours of attempting to call the call center (you can open an account in store, but Telkom does not let you close an account in store), eventually I took to a public platform (Facebook) and got an instant response. I explained that because I had not been able to contact anyone to discuss my options for migrating the line, I would have to cancel my services as I still had not secured my residence. Eventually they sent me a link (not hosted on the Telkom site) to download a cancellation form. I submitted the cancellation form and was told I would be contacted within 72 hours. 16 days later, and 2 follow ups from my side later, and I still have not been contacted. I received the same message word for word that they sent me in the past to say they would be in contact. Now I am being charged for a service I am not using. I have a new place of residence now and just want to transfer my line, but I keep getting the same automated message saying they will get back to me.
