Is there an application in your application that calls for support or chat support?
only email
It would be nice to implement the calls support or chat support

More and more people are using chat-bots - after all, getting a response from support immediately, and not a few hours later, is sometimes critically important.
In my opinion, it's much more effective to solve a question with a person, since the chat-bot does not know the all answer on your question.
I think, if you have some bot, that can answer to the most popular questions you can save some money and dont need so a lot of support or call centre.
