I would like to remove a person from my Gmail chat list and make it so she cannot contact me. She does not appear on my contact list. When hovering over her name on the hangout section it only shows two options. It says I can add to circles or the icon for video chat or message icon. It contains no contact information or e-mail information. She does not appear in my contacts section of my e-mail. She continues to send me messages and I want to block her but do not know how to do this. Help me please because this harassment has to end some day for me.
