I bought photoshop and I want to cancel the contract (should be possible within the first months). Now ist not possible to enter my cancellation. Who have I to send the cancellation? The changes in my account profile are not possible, as described below: http://helpx.adobe.com/de/x-productkb/policy-pricing/cancel-membership-subscription.html
The CC that you have purchased is of another country, that is the reason it can not be redeemed in your country with your Adobe ID.
As Ankit has mentioned, contact customer to check for resolution.
