Terrible customer service
Working with Intermedia has been nothing short of a nightmare. Getting the phones setup was absolutely awful and their customer service was atrocious. Then, two years later, we switch our wifi booster, and all our phones disconnected from the internet. After over 45 minutes on the phone with Intermedia, they proved to be no help other than telling us we should have the phones on wired connection (we've been using them wirelessly for two years). We were eventually able to connect to the internet by our own figuring out/clicking around on the phones. We will be looking to switch providers.
