Decoder ensurance policy cancellation

Since 2016 im am a Dstv subscriber (price lock) . Augus 2017 a sms informing me that my account is in arrears. I phoned Dstv and the matter was sorted.poligice and rectified the mistake. (Dstv appoligice for sending the wrong sms). I need to mentioned that my payments ismade by debid order. At the beginning of December I was notified that my insurance had been cancelled due to non payment. I contacted the Dstv and they confirmed that I'm R9.83 in arrears. I renewed my insurance and was informed that some of my condition (electronics) will only only be effective after a waiting period of 3 months. I think that Dstv is not professional and are not looking after their customers. The call I had made, cost far more than R9.83. I feel that this issue could have been handled off before hand, by phoning their customer to address the issue. Is there any other customers that experience the same situation?
