Telkom Complaint

After 22 years of living at the same address , I made a decision to relocate , which required cancellation/termination/notice to be given to Telkom. I duely did so, on the 31st of May 2018 giving notice to cancel BOTH my land line and ADSL line. This was done electronically after being told at a Telkom office/store that on-line cancellation was the ONLY way to give notice. On the 10th of July 2018 I vacated the premises and relocated to another area. Towards the end of July2018 , on trying to apply for a Fiber Network/Service provider at my new address , I was told by Telkom and Vodacom that I could not get fibre service as I had been blacklisted by Telkom for not paying off my FINAL account of R165,97, which by the way they were e-mailing to my ADSL line , which I had requested cancellation of and no longer had access to as it was supposedly cancelled as per my request and also because I no longer lived at the address. I was blacklisted erroneously by Telkom but fought to get my name cleared and duely got a letter from Telkom on the 27th of August 2018 , that I had made FINAL payment on my accounts and that I had been CLEARED at all relevant credit bureaux. About a month ago I suddenly started receiving DEMANDS for ANOTHER FINAL payment due for an amoount of R645.20. I got calls to be told that if i did not pay by the end of October 2019 I would be handed over !!!!! In one of the calls was cajoled into agreeing to at least pay R250.00 by 31October 2019 in order to show goodwill and not be handed over. They also sent me invoices that showed billing for a service i DID NOT request or know anything about , since 04 January 2019 at an address that I NO LONGER was residing at since July of 2018.!!! I have since Provided all relevant supporting documents, Cancellation of services, FINAL payment , and the letter from Telkom confirming I had made FINAL payment to the demanding authorities. I have not heard from them to say that they will investigate or that they have received my repeated statements and proof that once again they are erroniously billing me. I just keep getting sms reminders that I should pay my arrearrs and NEW FINAL account. So how does it happen that suddenly 14 months down the line get another FINAL payment demand and harrassment to pay or I will be handed over!! How many more FINAL demands am I still going to get???? Is there anyone out there that will listen to me and sort this out . I can no longer deal with a beurocratic system that does not seem to know what they are doing !!!!
