3rd Decoder not working properly in 1 month

Im so fed up with DSTV. our initial decoder would get stuck if you change vlume or channel or play a recording, we went to the custome care in Randburg and they provided us with a new decoder since we have the protection plan. Plug the ne decoder in an the RF does not provide sound. We take the decoder for testing they say nope decoder is working we must call an installer, we do that and guess what, it is the decoder. r450 paid for a callout fee for DSTV's fault. Then we rush back was assisted by a very friendly Lerato, and within seconds she confrims decoder is not working, she changes it for a new one. <br> Get the new decipoder it takes for ever to load new channels after changing. We phone they say decoder is still new, it will take time as it is updating to the new software, guess what its now a week and after watching a recodeing we need to reboot to be able to watch the current scedule. Not impresses at all by their service, and no I dont want a new Explorer, i want a decoder that WORKS please, the way our old one use to? Now we have to go back again DSTV.VERY DISSAPOINTED
