Dstv customer service

If you look in the dictionary @ 0% customer service, DSTV picture is next to it. I have been phoning since kast Thursday for help with xtra view decoder. On the phone they told me to bring in the decoder, there is something wrong with the software. When i took it to Multichoice Goodwood, they gave me a new power supply and said the decoder is fine. Up and down up and down.Someone promised to phone me back..... Still waiting,but don't worry, i will be cancelling my subscription. Thanks for nothing.
