Call Phone button missing in Google chat it was working yesterday - Google Chat Help: "Call Phone button missing in Google".
Google call phone are only available for US users, but people around the world soon found out that if you change Language settings to English (US), the call phone icon will appear in your chat.
But Google engineer seems to have changed the system, many people reported the button missing, I found mine missing too. People from US travelled to UK, found their the button missing in their laptop.
I have call credits, if Google don't let me use it, can I refund?
