    Chat Between Customer & the Seller

    Therefore, a new request for chat will also appear in your ChatWhizz window. You can either accept or decline the chat request of the customer.

    In case, if you want, you can also see the message of the customer before accepting/declining the request. After looking at the message, you can decide accordingly.

    One thing to note is that you can not reply to the customer until you accept the chat request. It means, you can see the message but can only reply when you accept the chat request.
