After I have removed and blocked a particular contact from my contact and chat list, when I search with the contact's name in the search option of my Gmail account, it still throws up the contact's email address with options to start a video chat, chat etc. I do not have the contact in my circle, neither do I have any mails or chats from this contact.
Why this behaviour?
What do I do to remove the contact completely?
Make sure you deleted it from all contacts, meaning from Other contacts as well. Also, in the chat list, you should have chosen Block, not Never show.
When you search for it and you find it, the very first item in that list is the box with his/her details (i.e. “it still throws up the contact's email address with options to "start a video chat", "chat" etc.”), right? There, next to the name you should have a small down-arrow — click on it and choose Edit contact details (see images below). This should send you to the contact’s details page where you can delete it from the More button in the menu.
