BEYOND PATHETIC

On the 25/06/2015 I did a premature cancellation on my number which I had to pay R 1200.00 I did it and emailed through and faxed through the proof of payment. Less than a month ago their Pre Legal offices phoned me stating I owe the money in which I said I don't I have proof it has been paid up. Now it turns out their Cancellation department never cancelled the line. I am not using the number anymore but they kept on billing it! Now I am being send from pillar to post and they expect me to pay the money! This is giving me a bad ITC score and It's not even my fault! I will never support them as I have been with Vodacom for nearly 12 years. I am fed up and I don't know what to do anymore. Logging complaints don't work phoning everyday is not working! This is ridiciolous. I now had to send an email to customer care but I honestly do not have hope or faith. next step I will sue!
