I've been with Optimum for a little over a year now and I have both positive and negative thoughts about the company. Call Quality My phone service is usually great but there have been times when I couldn't make outgoing calls, couldn't receive calls, and calls have been dropped for no reason. I actually had to contact customer service the other day because I couldn't make outgoing calls for 24 hours. They ended up having to reset my modem on their end. Features I think they have great features, especially DVR and exclusive access to News 12. Customer Service I am very happy with Optimum's customer service. Their representatives always go out of their way to help me. They walk you through all of the troubleshooting steps without rushing you. The last time I contacted them, they assisted me in finding a way to lower my monthly bill. And they can be reached via phone or live chat which is convenient. Live chat helped me last time when my phone service was out.
