Stonecold, I've been with the company for almost 5 years. You said mrv was free at install if HD DVR & HD were present and only 25 for DECA. I recently moved in June and I already had an HD DVR, and got a free HD at install. I asked the installer if he could do then and was told no, that I would have to call and he would have to come out again to install DECA. This made no sense because it was all new wiring, HD DVR & HD reciever but he had to come back to put DECA on and setup MVR? why not when there, 2 birds with one stone ya know. Anyways after calling back later to inquire about it, bam was almost 200, which is why I think things happened the way they did
The short answer is unless it not on the work order they are not going to do it.
Medium answer is it has to do with logistics , tech pay, times scheduling in our system
