Review chargeback response and decide on pre-arbitration or arbitration

Review second presentment for the chargeback and initiate pre-arbitration or arbitration, as required for the dispute workflow of the Chargeback stage. For Mastercard transaction chargeback, you can skip raising the pre-arbitration and directly raise the arbitration request.

Before you begin

Role required: sn_bom_credit_card.dispute_agent or sn_bom_credit_card.dispute_agent_connector.

Important: For the agent connector role to work, it must be combined with one of the CSM industry data model roles. For more information, see Roles and Personas.

About this task

This task becomes active when the merchant proceeds with a second presentment after the collaboration step is not successful. The following outcomes are possible:

Mark as Resolved: Review the second presentment, mark it as Resolved, and close the chargeback. The transaction moves to Financial adjustments 1.
Mark as Unresolved: If the second presentment is Unresolved and the cardholder decides not to proceed further with the chargeback, the transaction moves to Financial adjustments 2.
Escalate to pre-arbitration or arbitration: If the second presentment is Unresolved and the cardholder decides to proceed with the chargeback, then create a pre-arbitration or arbitration.
- If the merchant responds, the task progresses to the next stage.
- If the merchant doesn't respond within the specified time frame, a response from Mastercard displays on your Landing page and according to which you can manually take an action on the disputed transaction.
  
  Note: You can access this response from your Landing Page > Acquirer deadline expired tasks. For more information, see Dispute agent workspace

If Card Data Security is installed and configured, Attachments in the contextual side panel will handle files differently in transaction records. For more information, see Manage attachments in Card Data Security.
