How do I get off of a group I didn't join, in a language I don't speak, but can't delete?

The group also has a chat window that responds to every post. Here's the link. FB goes from having to have security clearance to add anyone to this.

Moved to facebook groups support

I found the remove button FB moved it from the bottom of the page.

Glad you could solve it!
