Fake way to recollect money though lying to appliers. / Fraud services

I received a call from a USAFIS representant laying to me saying that my file was selected by USA government to have the green card after a consular process. She explained all the following process and said I must present a consular interview in my country and later at any city where they have this offices in USA.

She said I must pay $3, 500.00 in order to have the support for traveling and having 2 months apartment close to the consular office in USA and to have the support of lawyers. All this information was not true. My file hasn’t been selected and they asked me to pay.

Now I want my reimburse and they are talking about 40%. Why? If they took my money through a lie?

Untrusted Company. Never apply through them. It’s an armed robbery.
