Annual payment messup every time

<p>Why can DSTV NOT recognise an annual payment? Why do I have to call them after the payment was made to tell them it is an annual payment?</p> <p>For years now I have been paying my account as well my mothers account annually. then a few months after the payment I get a call from their debt collectors and I have to sit on hold for extended periods while they do the maths to realise that I am not actually in arrears.</p> <p>Surely Multichoice can get their billing into line!</p>
