An agent that would not give up: four emails, three refusals, one reversed fee
When an app refused to review a small cancellation fee because the trip was over 90 days old, the user had an agent keep emailing until the company's grievance office acted, after four emails and three refusals. The amount recovered was tiny, so this proves the mechanism rather than a business: persistent follow-up is a sellable service only for disputes large enough to justify a fee.
