GetHuman has been working for over 10 years on sourcing information about big organizations like Comcast in order to help customers resolve customer service issues faster. We started with contact information and fastest ways to reach a human at big companies. Particularly ones with slow or complicated IVR or phone menu systems. Or companies that have self-serve help forums instead of a customer service department. From there, we realized that consumers still needed more detailed help solving the most common problems, so we expanded to this set of guides, which grows every day. And if you spot any issues with our What do I do if my Xfinity TV or internet is out? guide, please let us know by sending us feedback. We want to be as helpful as possible. If you appreciated this guide, please share it with your favorite people. Our free information and tools is powered by you, the customer. The more people that use it, the better it gets.
