Thank you for posting, @María37193661k499 .
I understand how frustrating it must be to have been trying to cancel your plan since August and still be unable to complete the process.
I checked the information available to us and found that you have 34 different accounts associated with Adobe. The active subscription may be under one of those other accounts.
When signing in, Adobe may display an account/profile chooser if more than one account or profile is associated with your sign-in information. Use the chooser to select the appropriate account or profile, then check the plans associated with it.
More information about managing Adobe profiles:

Since there are 34 accounts to check, I recommend contacting us directly so we can help locate the account with the active subscription and assist you with the next steps:
