CANCELLED CONTRACT, STILL BILLED

This is RIDICULOUS!!! I have cancelled my contract with Telkom mobile as of the end of March 2015!!! I am still being billed for a contract that I DO NOT want. I have emailed the retention office TWICE and gone into a Telkom mobile store to have the notes on my file updated to say I want to cancel or terminate my contract. But I have received yet another invoice from Telkom now for August....<br> <br> This is equivalent to theft in my eyes as I am being billed for something I did not agree to AND that I have actually out rightly stated I do not want either... Besides the poor reception and EXTREMELY POOR service, the call centre is very disappointing. I called to ask for someone to help me with this cancellation story and all I am told is that they can't help me, I have to email retention offices and wait for a call. According to notes on the system I have not been answering calls... that is all. No email or sms or any other form of communication to get hold of me. The number that was on the system was not even my number!! <br> <br> I am beyond unimpressed with this situation....I that I will not be refunded any money that's been debited from me!!! I am SO FRUSTRATED and ANGRY with this situation!
