Hi Flavio,
Sorry to hear that.
When you subscribe to the Adobe Stock promo offer, the first month is a free trial, Adobe doesn't charge you for the 1st month; the subscription billing actually starts from the second month.
If you cancel during the first month billing cycle, your credit card will not be charged and your service will continue until the end of that first month’s billing cycle. If you cancel within 14 days after the beginning of the second month’s billing cycle, you’ll be fully refunded. If you cancel the service after the 14th day after the beginning of the second month’s billing cycle, you’ll be charged 50% of your remaining contract obligation.
For more information, please refer to Adobe Subscription and Cancellation Terms | Adobe
Please reach out to our support team Support FAQ: How can I contact Adobe for support? for the billing queries.
In case you are unable to reach our support team through the above-mentioned link, please see Contact Support FAQ: Unable to reach support through the "Contact US" link
Feel free to update this thread in case of any additional questions.
Regards,
Twarita
