Need POE enabled on Port 8 of my CBR and Rack Mount Kit

I was on the phone with business service rep and she transferred me to freaking cloud solutions after she said she enabled the POE port on my modem but was unsuccessful at doing so.  Cloud Solutions is NOT who I need to be talkign to about this ugh...  And that darn IVR system needs to suffer a fiery death at the hands of an angry mob of Comcast customers.  It should not be that hard to get in touch with a representative!!!  I pay nearly $300/mo. for my services and when you spend that much money you don't need or want to have to answer 30 questions from a fake rep pretending to type on a fake keyboard in the background.

Also I need the darn rack mount arms for my modem.  AND YES THEY DO MAKE THEM.  At my employer we have the EXACT SAME modem and the install tech happily left a pair of the arms made specifically for that modem so that I could put the modem into the rack without having to mount it on the wall.
