A live chat is one of the several methods of communication supplied by some website hosting companies as part of their support services. Depending on the supplier, the chat is used for pre-sales, billing and/or technical assistance. This way of contact is quicker in comparison to a support ticket and it will make it much more unlikely to misunderstand or misspell a word compared to a call with an agent. Furthermore, if the issue that you have requires some time to be investigated and resolved, you are able to do something different meanwhile instead of just waiting, as you'd have to do if you call. Also, you can take advantage of a live chat support service without charge provided that you have web accessibility even if your hosting supplier is based in another country and they do not have a local phone number that you can call.
