Level of incompetence is astonishing

The service is appalling. I received an sms saying my account is in arrears. I made contact as a good client to find out what happened. After 3 attempts to explain what the issue is through the chat medium with no help,forth time we were getting somewhere until the connection flopped. The last lady,MBSLI ZONDO was a real piece of work!!!! Condensing, arrogant, grandiosity, nd dumb. The whole call was a pain!!! I told her that I personally walked into the branch on Main Street in Joburg and changed my debit order date from the 31st to the 25th of every month on the 24 of December 2021. She also told me that the system took a month to update which is fine. She then went on to explain the that I had missed payment on 31 January 2022.i continued to ask her if she had **** to me when she says my debit changed nd she said it on the 25th. I then went to ask her as to why was I not debited nd she said she'd check..she went on to put me on hold for over 25 minutes while assuming I would hang up...I patiently held on due to her instruction but Mbali Zondo thought she was smart in her actions!!! Such is the level of unprofessionalism from Telkom. Their managers don't even care to see what type of dispositions their agents use or even there to make sure their *********** agents are doing the minimum requirements of their jobs..is it company policy to make a client hold on for 30 minutes and then hang up with even checking if the query was resolved????
