Telkom still billing 4 months after account termination request

I would like to report Telkom for having me listed as a bad debtor for an account that I requested to be terminated. I had an ADSL account with Telkom (landline number ********** ) which I requested be terminated on the 1st of Sptember 2018 as I was moving out of the apartment where this landline was installed. Telkom said they would need 10-14 days to terminate and finalize the account. I visited the Telkom offices in Canal Walk (Cape Town) on the 19th to confirm if the account was finalized but was told it had not been done and would be escalated, dispute logged (Case # ********** 6). I then phoned the Accounts and was told that I owed 1,210.36 wich I resolved by October month-end. I however have apparently been billed for October and November and have subsequently been listed on the Credit Bureau as a bad debtor for an account that I terminated and settled. I have since October been fighting unending battles with Telkom with them promising to settle the matter and/or escalate but to date nothing has been done. The landline is inactive and that Telkom can verify. The other case numbers thatI have maintained track of for your consideration and ollow up on are: ********** 9, placed on 21 November, 2 ********** 38761A, placed on 21 November 2018 (this was when they confirmed they'd reserve the incorrectly billed funds, they promised this would take about 30 days)

21 December I again went to Telkom Canal Walk and still nothing had been done, the call centre agents promised they would follow up but nothing has been done since). I again went in 24 December and they again promised they'd check up on cancellation (nothing materialized)

I have been there and also chatted with their call center consultants several times last month (January, 2019) and all the time I am told it will either be escalated and/or looked into, but nothing seems to be moving. I believe inmy capacity I have tried to do all that I could but nithing seems to yield results hence my call and plea on you to assit in this matter

The latest case number I have is ********** 6 and this has been marked as resolved but I am not sure

Trusting that you will accept my plea and help bring peace to my case
