Mini Box Blues

I upgraded my TV package to the Advanced TV the end of October in the belief that I would be able to receive more channels on the mini box, since I only received 36 channels on it when I first got it and out of those 36, I watch NONE of them. I called customer service multiple times and it seems that every person I talked to had a different answer to my question as to why I was receiving only 36 channels. I received a reply on the last forum message I started, saying that they had found an issue on their end that might have been the reason why I was only receiving those 36 channels and that I should to a channel scan again and see if that helped. Of course, I did not change a thing. I was then told that once the conversion to all digital took effect, that I would receive more channels.. So, I unhooked the mini box from my tv, since the channels I watch regularly still played on regular cable.. Sadly, I woke up this morning to find all channels have now gone digital, so i hooked up my mini box and... Still only get 36 channels on it and still, none are ones I watch. I have a bunch of local channels, a jewelry channel, multiple CSPAN type channels, several spanish channels and some channels that say property channels. When I try to view one of my regular channels, it says I have to have a subscription... A SUBSCRIPTION?? Why do I need a subscription on one television to watch the same channels that I already get on the other television?? I asked on several occasions when I spoke to someone in customer service if the mini box could receive the channels I watch or did I have to pay even more money for a different receiver and it was almost an even 50-50.. Some said the mini box was fine, others same I needed another receiver.. I am about fed up and ready to find a new tv/internet provider...
