Telkom Not Refunding (*******)

I have been waiting 3 months now for telkom to get back to me regarding my refund. In September 2018 my line went dead (land line + internet) and not once did they call me. i kept phoning for them to fix the issue, but nothing. Only in October when i phoned again one of the consultants notified me that there are no copper lines in my area and they will not replace it. I decided to rather cancel the line instead of paying more for LTE and gave them the 30 days notice for the cancellation as they asked for and yet THEY STILL CHARGED ME FOR THE MONTH OF OCTOBER. Now i am waiting for my refund for the 3 weeks of September i sat without internet and also for the month of October. How can they charge me for the month of October (hte month i gave notice) if there was NO SERVICE BEING PROVIDED?! Since November I've phoned multiple times and i keep hearing "I will escalate the query, a manager will contact you in a few days" and still No one has contacted me. When i ask to speak to a manager, no one is available. They owe me over R 1000 and i want it back!
