Multichoice - profits over customer satisfaction !

I'm one very annoyed DSTV (Multichoice) customer. I have a explora ultra decoder that started to give trouble - it would not display the tv guide and also kept going into standby mode. After trying all the suggested options like rebooting etc. without success, I took the decoder to Multichoice Randburg offices. As I live in Hartbee****rt this was quite a way. Once there I waited for over 1 1/2 hours before being helped - fair enough they were busy. The technician that "helped" me could not fix the issue, so they replaced the decoder. After setting everything up and assuring me I would have no further problems I left. Once home and the decoder was connected, the tv screen kept flashing with a strange audile "clicking sound. I checked connections and rebooted the decoder, but nothing helped. I then phoned Multichoice and a very helpful young lady asked me for the decoder serial number. She then checked and told me that the decoder had previously been returned to Multichoice with a HMDI issue which would account for the issue I was experiencing. As I have full decoder insurance, Multichoice should have replaced my faulty decoder with a brand-new decoder, NOT a secondhand decoder that had NOT EVEN been repaired. I guess this **** is another way the fleece the public - a result of a company that has a majority and is ONLY interested in profits rather than customer satisfaction. What a DISGRACE :((
