Double debit for August 2015

On 1 August 2015 my account was double debited for the amount of R1558.00 instead of R779.00 for premium subscription. I contacted the client service center and informed the agent of the issue. I sent bank statements as requested showing the double debit and requested I get credited for September 2015. The agent sent the info to the accounts dept which ignored this flat out as I was double debited again in September 2015 which I reversed through my bank. Since then my account was placed in arrears for non payment in September 2015. I contacted numerous agents since and sent through bank statements showing the double payment however no one ever followed up or got back to me. I then landed directly with Confidence Khumalo who is one of the supervisors at the contact center. She also escalated my query however since the 19th of September 2015 nothing has been done and I've had to phone in every 3 - 4 days to explain the same story and send through the bank statements with previous comms to have my decoder reconnected. I also requested payment method to be changed to cash however I still got debited in OCT 2015 after paying cash on 30 Sept 2015. How does no one take ownership here
