Telkom debiting on the wrong date

<p>I have taken out a contract with Telkom in April 2017 for an uncapped data line and i informed them that i would like to pay via debit order. I instructed them to debt my account on the 20th of each month yet on the 19 May 2017 they debited my account and put my account in a minus also causing me to have a bad credit rating with my bank. The funds was then honored by my bank on the 20th May 2017. I then call Telkom on the 22 May 2017 advising them that they have debited my on the incorrect date and the agent advised me to change the date to the 25th of each month which i was then under the impression that my instruction has being actioned. To my surprise i received my month statement from Telkom on the 30 May 2017 and opened it on the 1 June 2017 only to find that the statement says they will debit my account on the 19 June 2017. I then called Telkom on 10210 at 09:41am and spoke to Phumiza and i asked her when my debit order will be deducted and she informed me from the 19 th of June 2017 and i told her i changed it to the 25th of each month. She then went further on to tell me that i need to make sure i have funds in my account for the debit order from the 19th June 2017. I asked her why my instruction was not put into place and she told me that i never gave them enough time to instate the debit order. How much time do you need to load a debit order if my instruction was placed on the 22 May 2017 and i am only to pay on the 19 June 2017 as per what Telkom wants me to pay. I gave them enough time to do the change of debit order date. I gave the instruction to change the date 28 days before the next debit order was due and Phumiza till me i never gave them enough time. I am really disappointed with the service i received and continue to receive from Telkom.</p>
