Telkom Incompetence

My name is Beverley I wrote a complaint about Telkom a few days ago. I still have not received any response from them. On Friday the 15 July I found out that Telkom went into my bank account and deducted the R803 from my account that I was still disputing with them. I am really disgusted and upset with the service that I as a loyal and longtime customer am receiving from Telkom. They are charging me R803 for an account that is R199 per month. All because of their own incompetence. I had gone into the Telkom store to inform them of my change in banking details on the 31 May 2022. They still went into the old account that is not active anymore and deducted which resulted in the debit order bouncing which is not my fault because I had gone into the Telkom store on the 31 May 2022 to give them my bank details and make sure that they change it. Now they charged me rejection fees for 2 months, and they expect me to pay R803 for something that is R199. I am so tired and frustrated with the incompetence of the accounts staff of Telkom. Now they deduct R803 from my account on the 15 of the month which was supposed to have been deducted on the 30July 2022. I really don't see that I have to pay rejection fees for their mistakes. Telkom really has to sort out the *********** staff that they have. I am retired where do they think a person must get extra R600 just to pay like that for their incompetence. I am really angry and disappointed in this service. I am still waiting for the email that the accounts consultant promised to send me when I called and explained everything to them. She said that she was going to send me a mail with a screenshot of my complaint so that I could see that she had captured everything I told her. I am still waiting. Is this the way that Telkom treats his loyal clients?
