Sound to me, the installer that installed your dish is the contractor's sub, and they are pay so low and not even able to buy a computer to learn the installation trick for this dish. There at least I know two sites to tell how to do this dish.
The pay part I agree with, but Circuit City is the retailer on this, and if the guys were rolling in a Firedog van or Scion, that means they were CC employees. CC is only using contractors for overflow, as I understand it. The only people that are gonna take these jobs are kids. I wouldn't take any job with Firedog outside of QC or management, because I know who they would be sending to unfck stuff like this.
Have you tried going into the store? Bring up their white glove service, and ask them about firedog culture......They say their mission is to make the customer happy.....
