poor customer service

I am deeply appalled by the apparent lack of respect and poor customer service that customers are subject to by DSTV. I mean to think that every month I spend about R1100 on my monthly subscription. I think lack of competition is the main reason customers are taken for granted. From the 26th august I have phoned DSTV in order to seek assistance with my TV to downgrade from north Indian and compact to just North Indian on one of my decoder it took about -5 minutes before I could go through, and once I went through I still did not receive assistance. I wasted my time and my R500 worth of airtime ran out. I then thought that it means that one must spend R500 worth of airtime just to get serviced and this according to my books is ridiculous. It's now the 8th September and one of my decoder is not on the rightful package. I have made numerous calls and I was told that there is a technical error on their side. This was supposed to be sorted out and has not been escalated to the technical department. I have spoken to the following people ref ***-I14 27/08/2015 Tetelo Dlamini ***-I14 02/09/2015, Thekisho Oageng 03/09/2015, Maneo Modise 08/09/2015 and the list goes on..
