I had QC come out after I changed my 625 to a 722, now I have a 622 and a 722. He sent the contractor out to change my LNB's because of the LNB drift. He also had them change the barrel connectors and the cable from the wall to the receivers. While they were here, they made it vey clear how they felt about QC. They said that they have never worked a day in the field and really did not know anything but how to work a remote. The QC then came back out to check on what they repaired and again did not like the way things looked. He said my signal strength was worse than before and they did not change one of the cables. He said someone would be out again, but after a week I have not heard a thing. Is there a way to check if someone will still be coming? Do the contractors always feel that way about having to come back out after the checks?
