Client Testimonials

Client

I hired Anastasia but All I got was her paralegals. So after finding out many lies that they said they tried to call my doctors or get information. My doctors told me they would not pay any fees to get my information. So they kept stringing me along. I terminated their contract after she told me that my benefits were denied. Then to billed me over $2,000. Come to find out she got the whole 4100 from social security and never told them that she was terminated. I would never ever recommend this company to anybody so now I have to get a lawyer
