No follow up or resolution

I would like to complain about the pathetic service I received from Telkom. I sent a request for a service cancellation on 12 FEBRUARY 2017 for my ADSL service and line rental. To date, my request has not been actioned and I am still being billed for both services. I have called Telkom several times, sending the original request which they acknowledge that they have received. Each time, I am told that "the call will be escalated and I will be contacted back". However, I have yet to receive any feedback on all. My latest call reference was on 18 August at 12:15 where I spoke to Clarissa. I still have not heard back from her... I am now fed up! Can someone please call me to resolve this issue!
