“Module 03’s evidence hierarchy changed how we reject incomplete merchant uploads. Module 04 still feels rushed if English is your second language — budget extra draft time.”

Learner notes
★★★★☆
“Solid flagship. The mini audit forced our lead to admit we had no sampling method — awkward, then useful.”
FAQ
Who should enroll?
Dispute analysts with at least a few months on a live queue, team leads preparing an internal review, and compliance partners who need to understand desk reality. Absolute beginners should start with Dispute Desk Essentials.
Is this legal advice?
No. The lab teaches operational judgment and documentation habits. Regulatory interpretation for your license remains with your counsel.
What is a real limitation of this course?
We cannot repair broken data pipelines. If your merchant feeds omit fulfillment timestamps, the lab will teach you how to document the gap — not how to invent missing data. Teams expecting a plug-and-play recovery-rate lift usually leave disappointed.
How are sessions scheduled?
Live blocks land in early evening KST to cover Korea-based desks. Recordings post within 24 hours. Peer reviews have fixed deadlines.
