If found if you get the screen with just the text in the middle saying you may want to come back later, that’s it.. never goes through to an agent.
If it goes to a screen that looks like a chat window with “waiting for agent” in a grey box at the top, wait as one usually says hi after about 10 minutes.
Tip off here: when you get the link to go through, don’t add all your details. Just add you name and email as quickly as possible (otherwise it takes too long and someone steals the agent)
