They say they are The Cash resource. They were trying to get me to take a loan over the phone. I tried looking them up on the internet but no reviews were shown.

I sent them $187.00 on a pre pay money back card, and was told I had to send in another payment of $249.00, I started getting suspicious. im now trying to get my money back. because I know its a scam.

You receive a call offering a loan, but you have to pay a fee up front?
It is a 100% scam.
It is against federal law to phone someone and offer a loan, but having them pay upfront:
http://www.consumer.ftc.gov/articles/0078-advance-fee-loans
"A loan that is offered by phone. It is illegal for companies doing business by phone in the U.S. to promise you a loan or credit card and ask you to pay for it before they deliver."

DO NOT EVER SEND MONEY TO A COMPANY THAT IS TELLING YOU YOU ARE APPROVED FOR A LOAN WHILE AT THE SAME TIME THEY ARE ASKING FOR MONEY. THIS IS A SCAM.

I'm sent them over 1000 dollars and still haven't seen any money. I have definitely learned my lesson. Should have known it was a scam when they asked me to send them money. Be careful!!!!
