Coursera Plus Charged After Free Trial Cancellation

I am a Coursera Plus user. While my free trial period was still ongoing, I decided not to continue with the paid subscription and therefore cancelled my subscription from my account within the 7‑day trial period. On the screen, I clearly saw the message that my subscription had been cancelled. Despite cancelling within the trial period, 29 USD was charged from my account on 18 October 2026. Being charged for a subscription that should not have been billed after a timely cancellation has put me in a difficult situation. I requested a refund of this amount, but so far no solution has been provided and the fee has not been refunded. I kindly request that the unjustly charged 29 USD be refunded to me as soon as possible and that the relevant subscription transaction on my account be examined in detail so that this issue is permanently resolved and does not recur.
