Telkom Call Center No One Ever Helps.

I've been having a problem with Telkom. I phoned Telkom on the 8th of March to my debit order from the 15th of the month to the last day of the month. The lady i spoke to (I don't remember the name) told me that the debit order change might only take affect from the following month as it is already the 8th but my payment is only due by month end. Which I understood. I advised her that i might not have money in the account in the 15th and she assured me that my account will be fine as long as it is paid by month end. I asked again " Will my account be fine?" and again she assured me your account will be fine as long as it is paid by the last day of the month. There was no money in my account on the 15th so the debit order bounced but it did go through on the 25th. So when I received my next invoice I was billed (Fined) R200 for the debit order bouncing that is not what I call my account being FINE. The lady spoke to assured me more than once my account will be fine as long as it is paid by the last day of the month, if there was a fine being charged she should have mentioned it and she never did. After I asked her two or three times. I have contacted the call center on the 9th of March and was promised that someone will call me. I called again on the 18th of April and was promised that someone will call me. I called again on the 18th of May and was promised that someone will call me. I'm still waiting for the call. All I get is promises that I will get phoned back but none ever phones. Being "Fined" R200 is not what I call my account being fine.
