@CollinsN ...
I am sure that Canvas Support has your ticket, and they will respond as soon as they can. As you probably know, this is the start of the new school year for many K-12 and higher education schools. I'm sure that the Canvas Help Desk folks are getting flooded with calls during this time...which, I assume, is expected. I know it can be hard to wait (I'm not a fan of waiting, either), but hopefully your ticket will be addressed by their Help Desk staff soon.
You said that not a single class was showing up in Canvas. Are you an administrator, an instructor, or a student? If you are an instructor or a student, you would need to talk with Klamath Falls City Schools' local Canvas administrator or someone from their Online Learning / eLearning / Distance Education department. They would be able to help you with any enrollment issues you might be experiencing.
You should also try going to your "Courses" >> "All Courses" menu within Canvas. Do you see your courses listed there? If so, they would need to be "published" by the instructor in order for students to see the content.
I hope some of this will be helpful to you. Sing out if you have any other questions about this...thanks!
