Branching to a new discussion,
I'm sorry you had a poor experience with Stock services and feel you were charged for the trial version.
However, when you subscribe to the Stock promo offer, Adobe doesn't charge you for the 1st month (1st-month free trial); the subscription billing actually starts from the second month.
Also, I see you have contacted our support team today and as per your request they have cancelled your Stock subscription and waived off the termination fee as a gesture of goodwill.
Feel free to update this thread in case of any additional questions.
Thank you for the prompt reply. And yes, my issue was solved. But I must say, the free trial offer is very misleading. Adobe is trying to get in the stock image market, I understand, but this was probably not a good marketing idea, as it left me not wanting to try or use Adobe stock again, specially with all the other options out there.
