Grammarly Charged Me $144 After I Canceled My Free Trial

I started Grammarly’s 7-day free Premium trial and canceled the subscription before the trial period expired. Despite canceling within the free trial period, I was still charged $144 to my account.

I do not accept being charged for a subscription that I canceled before the end of the free trial period. I request that the full $144 charge be refunded to my original payment method completely and without delay.

Please also review this issue and confirm why I was charged despite canceling the subscription before the trial period ended.
