DSTV unable to fix accounts

<p>We pay our Dstv annualy to get the 1 month free subscription. We have been getting constant sms's as well as messages on our decoder that we owe them money even after we called them and they gave us in writing confirmation that they fixed it. I have just received another sms with a different amount even after they confirmed that no monies are due until 27 March 2017. We are concerned that the dstv service will be cut off through no fault of our own. HOW CAN WE GET THEM TO DO THEIR ACCOUNTS PROPERLY WITH PEOPLE THAT ACTUALLY UNDERSTAND HOW THEIR OWN SYSTEMS WORK. We are constantly wasting our telephone costs, time and internet costs on a company that clearly cannot do ACCOUNTING. Useless if they confirm that I am right just to mess it up again. Will never recommend them or do a debit order with people who are unable to understand their own policies or basic principles of accounting.</p>
