content: Oh it is a bullshit excuse. TWC has a system that relies on a bar code scan of the equipment and if it is not registered with the system it DOES NOT WORK period. Modem, cable box, anything. You can buy your own but must take it up to the branch office for them to enter into the system. Sadly this does not waive the $5 monthly rental fee (they just call it an administrative fee, never mind it only has to be done twice. Activating and deactivating.) from the bill. May vary by representative you chat with but the one I get stuck with is a bitchy cunt asshole that no one wants there but sadly she still works there.
