Telkom wrong Debit dates ruining my Credit score

I have a problem with Telkom. I have two contacts with them. One for 10Gig data @R99 a month. And a Cellphone @R223 a month. On our agreement I asked them to debit on the 25th on my pay day. But they been debiting the data only on the 25th. Then they claimed that I said on the 5th. I have called them several times to ask them to change the debit date to 25th. They have agreed. I have it on writing a proof of me begging them. I been on errors because of this. They Charge me R200 extra for late payment. I find this as way of ******** customers their money. My account been late since December. Its been five months Asking telkom to debit on the 25th but they not doing that. I asked them who said they must debit on the 5th I get no Answer.

They can check their telephone records March 26 I spoke with two consultants who promised me that they change the debit date. Early in April I send them DM on twitter. They agreed that will bebit on the 25th. But they didn't do that. Only one debit. The R99 which comes to an end at the of May. My credit record is being ruined by Telkom Mobile on purpose. I have enough of them. I will never do business with Telkom ever again
