Equitable Acceptance Student Loan Forgivness Program Simple Repayment Plan Scam, monthly payments for a year. All fraud! Minneapolis Minnesota

They contacted me a year back and it all seemed legit, I googled them. Apparently not as well. After going throught paperowork and siging they gave me the good news that I was approved of loan forgivness ($15,000) and what I had to pay them was $1,500. It's been a year! $50 monthy payments, with $30 monthly increase to the $1,500. Nothing has been paid from my student loans, in fact, apparently I'm behind a few months. A whole year giving these scamers money. Now they wont stop calling me to "update information" only now they call as simple repayment team. I need help! How can I get out of this and get my money back!!?
