False Advertising / Pathetic Service

i received a call from DSTV regarding upgrading my experience on a Price Lock R949pm and free installation on the Explorer Ultra, biggest Mistake ive done, since the new installation i have endless problems, i have showmax and netflix, oh boy what a mission to get the apps on the ultra decoder, one says this, another says that, another one says i must take the decoder to Multichoice, pathetic, such a hassle, now everytime there is loadshedding and power comes back the extra view decoder gives no signal and waiting for primary decoder cant pick up the heartbeat from primary decoder, no one seems to be able to sort out this issue, i never had this problem before the new installation, the installer just pulls ups his shoulders saying thats not his problem, we must call Multichoice, multichoice says they cant do anything so WHAT NOW,, im thinking off cancelling and going back to my old decoders, now im checking my account i must pay R1159.00 for what when im supposed to be on price lock, false advertising..
