Poor poor service

Dstv needs to train their staff properly honestly for such a big company their service is appalling. I had a error code which they were unable to clear and was told that an installer needs to come out I asked twice if there would be a cost involved they said R300. Now I'm fighting with the installer I given as I need to pay R550 no Dstv was guessing they don't know what they charge. Should the consultant had made it clear that mam R300 is the call out fee and depending what needs to be replaced then there'll be an extra charge but none of that was said I was just given a flat rate of R300. I have received proper service and I guess they don't care as they don't have a competitor.
