Lloyds Bank has issued a stark warning to all customers as many people are losing out on £711 each, on average.
The banking giant said the number of "advance fee scams" jumped up by more than 80% last year.
Advance fee scams happen when a victim is asked to pay an upfront fee for goods or services that don’t materialise. This could be for a loan, to secure a rental property, or even a new job.
