Who can I call to get an issue fixed? I have reported a problem a week ago and not received any word or solution. I have called the main 800-203-6755 but no one ever answers even after leaving voicemails.

I have an issue that is needing fixed now, actually needed fixed last week. Who can help? My kids have been locked out of Canvas for a week and can't reset their passwords. I am using the Free for Teachers and had enrolled the students in my course. They were able to use it for two days and then got locked out. Their logins stopped working.
