I enrolled in this course under the impression that it was free. However, I am now being asked to pay in order to obtain the certificate. I have invested significant time and effort in completing the course and achieving good grades. It should be clearly stated at the start of the course that payment is required to receive the certificate, so that learners do not waste their time and energy.
