SA's Worst Service Provider

I have had so many problems with DSTV - this time (case no. SD ********** ) I wanted to watch a programme at 4pm so at 7.30am I called in and made sure my holiday home account was switched on and working (we tested it, all working). We all went out for the day and made a point to return at 4pm precisely. DSTV was not working and we missed half the programme we wanted to see. Naturally the charge for the day still gets raised! When I questioned what had happened it was explained as a "system failure". Why don't we have competition for DSTV in SA? Why does Naspers senior management not take action to sort out an appalling situation of poor management at DSTV?
