spartan bailbonds wont return my collateral after holding it for 8months ny, New York

i gave spartan bail bonds 7,600$ to get my husband out on 12\18\08. he never miss no court date or visited to the bonds office. the case was exonerated on 1/14/2010, i brought the exoneration paper to the spartan office on 4/02/10 on the receipt it said 90 business day for a return of my collateral deposit. it has been 8months and i haven't received a dime of my 5,800$ when i call the office they are very rude and hangs up on me, l went down there over15 times all they do is take my name and number but never call. i am getting tired of the games they are playing my brothers want to go with me the next time i go, but i don't want them to get into any kind of trouble. i just want to know what part of the system that let a man who suppose to be working with the courts rob people and don't do nothing about it, but if my brothers was to go down there and demand my money this same system will lock them up. i truly advise that no one use spartan bailbonds for anything its not worth the hassle you got to go thru to get your! money back.
