Coursera Charged $50 Without Notification After Free Trial

I enrolled in a course on Coursera that offered a one-week free trial. Being a student, I carefully considered my options, but at the end of the trial, Coursera charged me $50 (₺1600) without any prior notification. For a student, this is a significant amount. A simple email reminder before the charge would have been appreciated.

I feel let down by a platform I once respected for its quality education. This lack of communication has left a negative impression, and I no longer intend to take courses through Coursera. I request a refund for the charge and urge Coursera to improve its practices by notifying users before deducting payments. This would prevent such unpleasant experiences for future students.
