Customer Reviews for Internet Service Providers in Indiana

Frontier Fiber
October 08, 2026 When it works, it is good, but there is no real customer service. The site says you can call till 9 PM ET, but when you try, it tells you they are closed. The chatbot sucks and never knows what you are talking about. Their app works like it was made by a first-year high school student. The people chatting have to translate to whatever language they speak, so it is slow and not always in the right order; it is like talking to Yoda half the time. This is one of the worst places to deal with or get help when it is needed.
