Hello @MaimunaAhmad
Thank you for contacting the Instructure Community. We're sorry to hear you've been experiencing issues with getting access to your course. Are you trying to register or enroll in courses? If you are still waiting for an invitation to your course or need access and credentials to login to Canvas, you'll want to speak with your school or institution directly. They should be able to confirm you are registered with an email, confirm you have signed up for a course, assist with logging in, etc.
If you did not sign up with any school, institution, or company you can contact Canvas Support for more help:
