I missed the deadline for fighting a dispute - Can I submit a late response?

Late responses will not be considered by the bank. We recommend that you automate your disputes to avoid missing any deadlines. 

You can also set a rule to automatically accept (not fight) disputes that are overdue. This will help to keep your dashboard free of old disputes. This can be done on the ‘Workflow’ tab (click your name in the upper right, and then ‘Settings’. Update the ‘Accept Overdue’ settings and save your changes.
