Altice / Optimum Online is the worst. I signed up for gigabit. They came 3 separate times and tried to pull a fast one on me by installing a 200 mbps modem instead of a DOCSIS 3.1 modem. On the 3rd visit, I had my own Arris SB8200 ready, and had the tech install it, and take their modem back. I've spent more than 20 hours on the phone with them and they refuse to remove the modem fee. I assume they will eventually charge me for a modem I already returned. I have the work order PDF showing their modem was taken back by the tech but since they continue to bill me for the modem every month, they will probably screw me, with an unreturned modem fee, when I finally cancel service with them. I don't think there's a company in the world that I have more scorn for.
