Telkom's billing me on a line that was cancelled in July 2020!

Hello , I would like to share my terrible experience with Telkom. In July of 2020 I had cancelled a landline with an ADSL line and a seperate internet Data package. I was given two case numbers . An email was sent as well to confirm the cancellation the request. I had paid the two months bill according to the cancellation rules . I was then sent an sms a few weeks later to state that the case numbers were resolved. Suddenly in October I was sent an invoice for the landline. Went back to the Telkom Store in Cresta, queried it , gave them the case number etc. They sent me home and was assured that the matter would be resolved. Then in December , I was sent a bill again for R 1 000 , this time I was told to call Customer Services the billing department , repeated this whole process again over the telephone, now my account was standing at R 1600 and something. Firstly , how can I be billed for something that is not even being used? They claim that the line is "active"which is ridiculous as I no longer have a telephone at home and they can see that no calls have been made since July. While all of this was happening , I had app**** for a migration to fibre with Telkom in my area and now they have cancelled that application stating that there is no coverage of fibre in the area ( which again it is ridiculous as they have been campaigning this door to door promoting fibre in Crosby, Johannesburg), and that I owe them money. So now again, I go to the store at Cresta , only to be told that they will call Telkom to give me a call back. And there I go again repeating this whole process again. I am so frustrated at the incompetency of Telkom. Today I was given a new reference number, told again that cancellation request has been sent through , I must wait for the invoice for this month , and only then will they lodge a dispute on my account which will now stand close to R 2000. Who has R 2000 laying around in our current economic crises. I will get a bad credit rating because of the mismanagment of Telkom this is unfair. I need help to resolve this matter or I will be taking this matter up with Headoffice or the Minister of communications because I am sure that there must be many clients experiencing the same problem with Telkom and yes I am tax payer, so Telkom get your act together and sort this mess out . I will not be paying this amount , when I have paid the account according to the cancellation procedure , given to me by the Telkom store. I will be waiting for a response from Telkom because I will not go through this dance all overs again when we have other imprtant bills to pay etc. My email address : ***
