DSTV installation

The company with the worst service ever!! Oh wait, they don't have any service at all. 2 weeks ago I contacted them to apply for the DSTV Explora decoder and installation. According to the DSTV tracker, the installer would have come on Friday. I took a day's leave and nobody pitched up. It was changed to Monday 18/03, and again nobody even bothered to contact me for an appointment. However, according to the DSTV tracker, my DSTV is activated and installed. RIDICILOUS!! When I tried to phone the installer they provided on the DSTV Tracker, the number belonged to somebody else and nobody at the call centre can assist or tell me what to do next. I am not going to get billed for a dstv activation that did not even happen
