I am not sure about calling them , but a bit of a workaround, there is a chat option, that is to a live person and is or can be helpful.

if you click the question mark icon

It is mentioned here "Contact Google Workspace support" https://support.google.com/a/answer/1047213?hl=en 

You have to have a Workspace account to do it and to log into it, you don't use the email address you used to create it. You use a username that is a username/"email address" they email you which is blah@domain  where domain is the domain you told them.

Then you are logged in as admin to google workspace, and it will show the question mark, and so you can then click the question mark and from there, get to the chat.
