Welcome to the worst call centre in the world.

Customers dial what they think is Lumen Federal Bank's help line. It's you. Each one has four details worth $200 apiece:

• Online banking username XX-XX
• Online banking password XX-X-XX
• Account number XXXX-XXXX
• Card PIN XXXX

Talk them into reading each one out, type it into Account Link, hit Verify. Push too hard or slip up and trust drops. At zero they hang up. Six calls per shift.
