No service

My DSTV has no sound since yesterday. I have tried all methods of communication with them but no response. I have e-mailed, tried self-service, sent a direct tweet, called the call centre. NONE of those are working, no response.<br> <br> This is happening for a second time in less than a month. I need this sorted out URGENTLY and PROMPTLY, because when they calculate the money to be paid they count the NON-Service days like this one in question.<br> <br> DSTV's service is unprofessional and unacceptable.<br> <br> Thank you
