Subscription Stopped, yet Billing continues

March 2015, I logged into my online profile for self service. I switched off all my Subscriptions and services for all DSTV related products. The only product i kept was the Decoder insurance. On the 23rd of March I phoned DSTV to make sure that my services were off and that no money will be Debited in April. The Call center agent said that my subscriptions were still active. I asked him to cancel everything except the Decoder insurance. I got the following reference number: ***. The call centre agent's name was Sidwel, The call took place on 23 March 2015 at 12:30 and he confirmed that he cancelled all my services and the debit order will not go off , except for the decoder insurance. 1st of April a DEBIT order of R676.33 went off after all of the above stated. On 2 April 2015 I Phoned in to find out what was going on. The lady who helped me said that everything on the system is cancelled with regards to subscriptions and that the problem is on the system since it Debited R676.33. She advised that I roll-back the debit order and I did. Sunday 5th March I receive an SMS that says R676.33 Unpaid. Please pay Immediately. Please sort this out. IT IS NOT ACCEPTABLE!!!
