To ask for an advance fee to obtain a loan is illegal in every State of the USA. If you paid money by:
(1) Credit card, call your card company & dispute it.
(2) Check. There may be a chance. Call your bank
(3) If you used a cash wire transfer service (Western Union, Green Dot, etc.) or prepaid credit card I am sorry to tell you your money is lost. This is cash & can be picked up anywhere in the world.
