When your hosting supplier provides live chat support, you will be able to talk to an agent live and find out useful info or get a problem resolved in a timely manner. The key advantage of using chat compared to calling to talk with a live person is that you'll need only a computer with web access, so that you won't pay any rates in case you're in a different state or country. Furthermore, it is a lot easier to copy and paste information such as domain names, usernames or error messages in other words details which are sometimes hard to provide to the other side on the telephone. The live chat is also a much faster way to contact your website hosting company's support crew compared to using a ticketing system. Last, but not least, when some trouble requires a little more time to be resolved, you are able to do something else entirely while you wait for support on the live chat, so you will not lose time - something that's not possible in case you are on the phone.
