Debit Date

I have battled getting my debit date changed, after months of struggling and a Hello Peter complaint Telkom Agents finally assisted. Now I'm struggling with the Call Centre agents because Telkom has debited my account when there's are no funds and before my date requested. Who is liable for MY bank charges and Telkom penalized me for no payment on top of that. To add to my frustration I speak to Mahole and send an email with no reply, I call on the 10th Sept and speak to David that is to clever and lacks listening s****s. Can you as a reputable establishment Company please debit my account on 25th and if the debit date falls is over the weekend debit my account on the Monday after the weekend.
