If your hosting provider offers live chat support, you'll be able to speak to a representative live and learn useful info or get an issue resolved in a timely manner. The basic advantage of using chat compared to calling to talk to a live person is that you need just a computer with web access, so you won't pay any rates if you're in a different state or country. Furthermore, it is quicker to copy and paste information for example domains, usernames or error messages in other words details which are sometimes difficult to provide to the other party on the telephone. The live chat is also a much faster way to contact your hosting provider's support team compared to using a ticketing system. Last, but not least, in case some trouble requires a little more time to be resolved, you can do something else entirely while you wait for assistance on the live chat, therefore you will not lose time - something that's impossible when you are on the telephone.
