This is not Adobe. Rather user to user.
If you have purchased the product as a download from Adobe within the last 30 days, you can ask Adobe for return/refund.
Please see the following
An alternative route, not sure if it will get you to the same place.....
Membership, Account, Payment
Payments, Invoices, Orders
If you have purchased elsewhere, then the return/refund needs to be handled by the seller under the return/refund of the seller.
Please let us know if you have any questions or need clarification on the above.
