Event Description
As debit card usage continues to rise, so do customer disputes — from unauthorized charges to billing errors and merchant disputes.

This practical session will walk through the full lifecycle of a debit card dispute — from intake to investigation, provisional credit, and resolution.

Perfect for card services, fraud, operations, and compliance teams.
