Ok, now that the tree is gone, all the wire has been replaced, the receivers have been replaced.... I'd say it's time to completely replace the dish, reflector and LNB..
I'd call the company that put it in and tell them to put a brand new dish in, I personally either think that the installer either didn't swap out the LNB like he said, or the dish has some kind of flaw, maybe a dent or something throwing off your signal.
I hate that you have been having this much trouble with your system bill, unfortunately, this is the kind of install companys, and installers that give satellite a bad rep.
