first security preparation making me pay a arm and a leg for my certificates manhattan, New York

Hello, well im been told dozen of times that you not suppose to pay, no $360.00 for you two certificates. Thats how much they trying to get me to pay. I did not pay it yet, but i already payed my $80.00 dollars to them already, and took my 24hour classes. Im not even sure what to do now, or i know is i need a job asap, because im moving soon, and rent have to get payed. My girlfriend was suppose to receive a job with them, but she had a felony, but they told her it wont affect her from seeing a job. Then weeks later after she got interviewed they told she cant work cause she is a felon AFTER!!!!!! she payed her $80.00 dollars for it. So i dont know about them i saw and heard to many things so i dont trust giving them that type of money.
