Change of bank account details not activated

I was surprized to find that Telkom had debited my old bank account for this month's payment when I had notified them of the change on 15 May.

15 May 2018: Notified Nosipiwo of my new bank account details. She said the first deduction would be towards the end of June.

26 June 2018: Asked Zindi why the deduction had come off my old account and she said that although the details of the new account had been captured, the account had not been activated.

Spoke to her supervisor Yondela to express my displeasure with the poor service as had the old account been closed, I might have had my service disconnected. She apologised and said that the new account had now been activated and that she would report the matter to Zindi's supervisor.

I will be closing my old bank account tomorrow.
