My install should have been completed last week, but due to some mistakes by the installers, they couldn't get the job done (details here: http://www.dbstalk.com/showthread.php?t=145006) The installers cancelled the work order due to "Line of Sight" and asupervisor was supposed to call me to come out for a second opinion. It hasn't happened. I've called the install Co. twice and D* once. How do I go about elevating this? Do I need to call D* retention?
