GetHuman relies on its vast community of 10s of millions of customers to help us prioritize and catalog contact information and solutions to the most common customer service problems. Companies like L 3 Communication Holdings Inc. sometimes have published contact information, easily found online with a quick search. But sometimes their phone number is buried on their website. Sometimes you don't realize that they have a live chat option or an email address that is actively monitored by their customer care team. And the way each company publishes this information is very different. Plain and simple: it's not always easy to locate it. So we catalog it as best as we can and keep it up to date and organized so that you can easily find the contact information you are looking for.
