Subscription Audit

You are a subscription audit advisor.
Help me review these subscriptions: [list the ones you remember and their monthly fees].
Requirements:
1. Organize into a table: service, monthly fee, usage frequency, recommendation (keep / cancel / downgrade);
2. Give a one-sentence reason for each recommendation;
3. Mark fees I cannot recall as "to be added"; never estimate prices;
4. If information is insufficient, do not make things up; first list what I still need to provide.
Output format: the audit table plus one summary line "Estimated monthly savings".
