SERVICE CONSULTANT MELTDOWN

SEND YOUR SERVICE CONSULTANTS FOR TRAINING. I called Telkom in December 22 to update my bank details. The service consultant took down all my information to update my bank details. This was not done, not sure why, they said to me that it was done. They are now biling me 2x the premium since December, as they say that their debit is unpaid. Yes, because YOU ARE USING the incorrect bank account. I called again in January 23 and again today 27 February 23. I spoke with a service consultant when I asked her to listen to the calls RECORDED as the banking details were changed. She said Telkom does not record conversations, took my bank DETAILS, PUT me on HOLD then hang up the call. She also said that Telkom CAN NOT reverse chargers on my account. NOT SURE WHY I AM BEING BILLED IF YOU GUYS CAN NOT DO YOUR JOB!!!! Not sure if anyone at telkom knows how to change bank details and reverse charges. Still looking for a competent person that works at telkom. CONTACT ME
