Yes, my sponsor said they cannot complete the course.
In that case they must give you the option to receive a full refund of the course fees or your sponsor will reschedule it with you if you want to.
How do you know for sure if the person who registered with the course is the one who actually takes the course online?
Each sponsor has methods they use to make sure the right person is taking the course and if a person is found to defraud the system they can be prosecuted.
