Very poor service from Telkom

I had 2 accounts with Telkom. One is to be deducted at the end of the month and the other at the 5th of each month. Both are up-to-date paid. Telkom is deducting the one that is supposed to deduct the 5th now at the end of the month and the one for the end of the month not at all - I need to eft every month. On the 20th of July, they tried to deduct again from my account and I had to pay a penalty fee. Received a sms to confirm my payment !!!!!
