A live chat is one of the several ways of communication supplied by some hosting companies as a part of their support services. Depending on the supplier, the chat can be used for billing, pre-sales and/or technical assistance. This way of communication is quicker compared to a support ticket and it'll make it much less likely to misunderstand or misspell anything in comparison to a phone call with a representative. What's more, if the problem that you experience needs some time to be reviewed and resolved, you'll be able to do something different in the meantime instead of just waiting, as you'd have to do when you call. Also, you can take advantage of a live chat assistance service absolutely free as long as you have Internet accessibility even when your website hosting supplier is based in another country and they don't have a local phone number you can call.
