Disappointed subscriber

I took my decoder for assessment. After waiting for 2 hours, I was told I had to replace it at a cost as the hard drive had packed up. Coming home, Showmax doesn't work and my other decoder in the other room is not working. When I.called them again they told me to call my installer. So I'm paying more than R1000 a month and still can't watch my TV and no wants to help me. Multichoice is the most useless company by far.
