If your hosting service provider provides live chat support, you will be able to talk with a representative in real-time and learn useful info or get a problem resolved timely. The main advantage of using chat compared to calling to talk to a live person is that you need just a computer with Internet connection, which means that you will not pay any fees in case you're in a different country or state. In addition, it'll be a lot easier to copy and paste info for example domains, usernames or error messages i.e. details that are sometimes difficult to share with the other party over the phone. The live chat is also a considerably faster option to contact your web hosting service provider's support team in comparison to using a ticketing system. Last, but not least, in case some problem needs a little more time to be dealt with, you're able to do something different while you wait for assistance on the live chat, therefore you will not lose time - something that is not possible if you are on the telephone.
