Telkom daylight robbing customers.

My contact with Telkom ended about 3 months ago. I called in before my last deduction to cancel. Telkom deducted money from my account which was not available due to my contract that ended.I called numerous times even asked to speak to a manger ,which the last I was promised to be called back. Last month they deducted R1196.49. I called again there after only to be told there was an amount outstanding and because monies were not available they added charges. Then I was told the contact was not cancelled. I cancelled it again only to receive an invoice now that I will be debited R1457.25. Where is are these amounts coming from, I’m not even using that simcard nor do I have money to pay. My bond was short due to this unnecessary deduction. The service is disgusting and not forgotting the long hold whenever i call in
