How can we email or chat to Garmin for S62 support?

I used to be able to navigate to a page that had a contact form and a live chat option for support. The contact form was broken, it would not submit your message, and the live chat was almost always unmanned, at least in my Asian timezone. However the 1 time there was someone in chat, it was a US friendly time, they were very helpful.

But I can’t find that page anymore. So how can we email or chat to Garmin for S62 support?
