Use cases
Real accounts of agents doing this kind of job, each linked to its source.
- Get a car service quote without waiting on hold yourself
The agent sat through the hold queue at a San Francisco tire shop and came back with $129.99 for a standard alignment, about $210 for lifetime, and word that walk-ins take one to two hours.
- Book a lawyer consultation and negotiate the fee down
A Michigan firm quoted $400 for a consult on software law. After checking with the user, the agent negotiated a 30-minute phone consultation for $300 on a weekday evening.
- Get a cable company's retention team to lower your internet bill
The agent said 'cancel' at Spectrum's phone menu to reach retention, waited about five minutes, then patched in the account holder when the rep would not deal with an assistant. The user came away with $55 a month for a year instead of $85.
- Ask a store to hold an item for pickup today
With a gala at 5 and a broken shoe, the user had the agent call a Men's Wearhouse to hold a specific pair of loafers in their size. The associate set them aside under the user's name with no card needed.
