signal gets cut off continuosly.!!!

I installed an explorer with x-tra view, as well as a secondary decoder in Dec 2015. I phoned to get it activated. Since then my signal has basically been cut on a weekly basis. First on the one decoder and then on the explora.<br> Apparently the case has been referred, as they had it on 2 separate accounts. Every time I call in to get the service re-connected, they escalate the case. every time it costs me a telephone call for half an hour to an hour. Today again my signal was cut.I am fed up with multi choices *********** people.
