The system we use (CSG - Pretty much the standard system throughout the industry) will not allow any modifications to an account when there is an active work-order. This means changes to programming, activating receivers, etc. What we CAN do, is ask if you don't mind us cancelling the work order, activating it, then setting up the work order again - it may result in losing the original date, and it may not. They are SUPPOSED to ask you before you do it, but sometimes they just go for it if the date is very far out. Some of the techs also are not telling you if the date is cancelled, and they set it up for one nearby, so when that date comes, you suddenly discover it's set for a week later. They are NOT supposed to do that, and it makes life difficult for the rest of us. *grumble*
Gutter: As a business rule, we require the 622 to be installed by a "professional Installation Technician" before all is said and done. You probobly know how to hook it up yourself just fine, but just remember that some people also think they can hook it up just fine, and wind up using a regular TV splitter on a single cable that used to be for their 301 receiver, coming off a standard DP-Twin, to get the line into both Sat In ports. Which, of course, causes problems.
