Incompetence

I spoke to Londiwe Sokhela on 07/09/2021 to change bank details. Londiwe confirmed that my bank details have been changed and the payment will go off from the new account month end. I have changed bank details previously so I know that that would not be possible but gave her benefit of the doubt as she confirmed with her manager. Come month end of September the debit went off the old account resulting in me having to make a manual payment (and incurring bank charges) so I assumed that come end of October, it will go off my new account as confirmed, my bank details were changed. To my surprise, it went off the old account again, resulting in me having to pay via eft (incurring more bank charges) and now I am being charged by Telkom for a returned debit order, all due to the incompetence of Telkom agent. I want my bill rectified as I will not pay a returned debit fee due to Telkoms mistake, fix this or I will escalate beyond HeloPeter.
