Not receiving signal - matter not being resolved

I am frustrated and very angry at the complete lack of service that I'm getting from DStv. In June DStv apparently changed their admin system. In the process my older PVR was removed from their system (supposedly 'lost' by admin). Since then I can't watch dual-view and only receive a signal on my HD decoder and not the older decoder. Since October I've reported this and tried to get the matter resolved. The signal was briefly restored early in November but then ceased after a few days. The call centre doesn't help. The supervisors supposedly 'escalate' the issue but never get back to me.I dealt with a supervisor called \Boitumelo"on Friday morning and was given yet another reference number. He promised to discuss the problem with the 'technical team' and to call me back on Friday afternoon. I haven't heard any more since then. DStv are happily charging me for a service that they are not delivering. I want to know what they're going to do about it. Both to IMMEDIATELY restore the service I'm paying for as well as refunding me for the service that I haven't been receiving. """
