Debit order incompetence

I am very upset with telkom accounts right now. I took a contract end of August and my first debit was due on the 30th of September which they did not debit. Today is the 11th of October and nothing yet. If they had debited only to find no money in my account they were going to add an extra 200 rands but now that the fault is on their side nothing has been communicated no reason whatsoever why the debit hasn't gone through. It is very upsetting I have kept the money in my account for as long as I could. I can always be in panic when my account has less than what they have to debit net because of their incompetence. Let it be noted that they can debit end of October not anytime from today and there after is should be professional and be debited on the agreed date. it is very upsetting.
