Amount refund request

So, basically I opted for a free trial in acrobat for acrobat premium subscription.But,now I don't need it anymore . But I forgot to turnoff Autopay . So , the money are automatically deducted. Could u please guide me how to get refund or any other alternatives to get my money back ? And the payment is done just an hour ago.So,I sincerely request you to look in to my issue and resolve it at the earliest.
