Did you cancel the subscription in time (at least 24 hours in advance of renewal)? If not then you may be charged and if you are charged you have to pay for it. I have never seen anybody post here about Apple "cancelling" a charge in your situation. Pay what you owe and then ask for a refund. If you are fortunate you may receive one but they are not guaranteed.

Notes:
• “If you signed up [which involves very intentional steps by you or a user of your device, accompanied by warnings along the way] for a free or discounted trial subscription and you don't want to renew it, cancel it at least 24 hours before the trial ends." Note that by using an app like this you are automatically agreeing (always read the fine print) to this happening, are responsible for reading if this will happen, and canceling the subscription before the trial ends.

• Deleting an app does not cancel a subscription.
• An existing subscription will normally continue until the end of its term and may then renew automatically. Stopping automatic renewal is effectively canceling it. "If you don’t see Cancel Subscription, then the subscription is already canceled and won't renew." The "Expires" date means the current subscription will just run until then.
