FastCash Shawn Gibson, Edward Smith, Nickolas Hall they took my money saying i was getting a loan and never paid me miami Florida

Shawn Gibson from fastcash.com called me and said i was approved for a loan of 3000 dollars, all i had to do was get a green dot moneypak and put the first payment on it so they could get it. I loaded it with 150 dollars and called them back, they took the money and told my pre-paid debit card information and said it woud be added to my account. It was never put on their so i called them back and they said they gave my application to a loan company, so they transfered me to an Edward Smith that told me since i had a low credit score i would have to pay another 499 dollars to raise my credit score and recieve my loan of 3000 dollars. So i bout another green dot moneypak card and loaded it with 500 dollars. I called Edward back and gave him the greendot moneypak card number and he took the payment and said the money would be put in my account the next morning, and it never was. I called them back and they wanted more money so i told them i wanted to cancelle it all out and wanted my money back, they said they couldn't give my money back to me.
