If your hosting provider supplies live chat support, you're able to speak with an agent in real-time and find out useful info or get an issue resolved in a very timely manner. The main advantage of using chat rather than calling to talk to a live person is that you will need just a computer with Internet connection, so that you won't pay any charges in the event that you're in another country or state. Furthermore, it will be a lot easier to copy and paste info for example domain names, usernames or error messages in other words details which are sometimes difficult to share with the other side on the phone. The live chat is also a faster way to contact your website hosting provider's support crew as compared to using a ticketing system. Last, but not least, in case some problem needs some more time to be taken care of, you are able to do something else entirely while you wait for support on the live chat, which means that you won't lose time - something that's not possible if you are on the telephone.
