debit orders placed without my authorisation

Hi I fell on some difficult times in early January 2021 so I called Telkom to make a payment arrangement. After contacting Telkom on more than four occasions I eventually came to some type of agreement of which I have honoured. One has to consistently call them to make sure that they have the payment arrangement in place. My debit order is set to go off on the fifth of each month, yet they have tried twice to debit my account (15 and 19 Feb 21), but I only get paid on the 25th of each month. So the forced debit orders from Telkom is ******* without notification or consultation and it cost me R220 on banking fees. Seriously for a company that is operating for over 30 years, your billing system is still not yet up to scratch. Please reimburse me with R220 as your billing seriously needs some rework.
