That's ridiculous! If you return all that, then what is the next person going to use if they want Cox? I've never had to return outside wires and I've moved 3 times. Twice, they had to replace the wires, because they were just for cable TV, not for internet, so they had to install the internet wires. Once they had to upgrade the wires because the ones in the apartment were too old to work with the newer internet connections. Nobody ever told me I had to return wires. I returned my rented modem, and that was that. Never heard anything else about it.
