SmartThings support chat

Does anyone know how to contact SmartThings support via chat or email? SmartThings Support link on this page lets to start a chat session, but operators there say it’s “Samsung products support chat, not SmartThings”

In the ST app, the only options are Call us and Text chat. I know that they discontinued their email support because I got this response when attempting to close out an open case.

Hello,Thanks for reaching out to receive support with your SmartThings system.
This email address ( is no longer being monitored for support requests, but we are still available to aid you with any issues. 
Please follow the link below to find various other ways to get in touch with us so that we may assist you.

Actually, it’s the same link they have on SmartThings Support page, but it leads to a chat which rejects providing support for the app. It looks like phone call +1-866-813-2404 is the only option left.
