Bad service from Telkom

On the 23 May 2020 I was given a wrong contract option the consultant has to correct it and give me the case number which is ***1 and I was called on 28 May by the person who was helping me to say the matter was resolved I can come to collect my phone which I did. On the 15 June 2020 Telkom debited R 6947.90 and R571. 78 which I reverse R 6947.90 and I call the customer care service which they give me the case number ***1 then after I call the person who was helping me at the shop and they promised me that the matter is being attended too. When I call the customer care service they keep on saying that the case is with the finance department they is nothing that they can do and promises to send the message to them and they will come back to me. On the 15 July they made two debits on my account again which are R4777. 24 and R329. 00 which I made a reverse of R4777. 24 and again call the customer care service and they promise that the matter is being attended and the new case number is ***8 and I waited for them to come back to me on which they did not happened. On the 4th August 2020 I make a follow up and explain to the consultant over the phone again she told me that what I am telling her is not reflecting on her system and she will launch a new case ***9 and on the 5th August I then receive the email and the SMs that stating that I am in errors of R7349. 60 and they have suspended my rooter number stating that due to collection. My problem is that I have been trying to resolve this issue and I have to go out of the house in this COVID-19 go to the bank to reverse the money and I have tried to get this matter resolved but I am not help in which this matter affects me on my bank with reversal fees that the bank charges me....
