Incorrect billing

Been calling Telkom since early June and ive spoken to a number of *********** individuals to sort out the recurring data on my contract. All these IDIOTS have been telling me 1 thing, that they will either escalate my query to their line manager or get that damn manager to call me back. No one has gotten back to me and i keep getting billed for nothing. I have no other alternative then to send this to ICASA
