What they did

With access to Hotmail and the maintenance history, the agent reviewed 80,000 emails, flagged more than 20,000 old promotions for deletion (with explicit approval), logged every action, opened a chat with the internet provider to claim a refund and scheduled the air conditioner service.

How it went

The inbox dropped from 96% to 60% full; the refund date was confirmed.
