Mediacom Cable
May 14, 2023 I have used Mediacom for about 11 years. They are really good about keeping the service up and if it does go down they have a recorded message to let you know about how long it will be. I have had in the past also called them when the pricing increased and was able to work with them to get a very good deal. Overall I would say Mediacom provides excellent service and has very friendly representatives.

February 03, 2023 My husband and I both work from home, so a reliable internet connection is very important. As soon as fiberoptic was available, we signed up. The connection is fast and consistent, and if there is an issue it is resolved quickly. The price is well in line with the other services available in my area, but the speed and service is unbeatable.
