Still being charged after canceling months ago

I cancelled my Telkom line several months ago. I still was being charged monthly - I eventually got hold of the call centre last month and was told they had escalated my issue and my money would be refunded (The ref. no to that call was ***0). This morning I see another charge was taken off my bank account!!!!!! Telkom please cancel my account and give me back all the money you owe me including my deposit. This is disgraceful. You are now *****ing. I'm done speaking nicely to call centre people and staff in Telkom shops. Please sort it out or I will need to go to the CCMA. Please I beg you. I don't have money to be taken from me for no reason.
