Barclay Career School School just disappeared leaving me the graduate with no forwarding information Washington, DC Dist of Columbia

While in the classroom a couple of nights a female student yelled out this class is bogus.  I've been in other paralegal classes in other schools and these people are not teaching us the right things.  

I have been trying to find this school because I am constantly struggling still trying to pay back this loan which has trippled by now, but no school can be found.  In order to get a good payng job in this field I need another copy of my diploma.  My word is one thing, but some people require the actual document.  

Yes, I did finish the course and receive my Paralegal Diploma.  I moved a couple of years later, and it was lost or stolen prior to the move.  So I have been trying to get another for years.

I remember that the classes were pretty full every night.  I graduated in 1992 or 1993.  Can We Please Do A Class Action Suit against the District of Columbia for allowing these people to take our money, not properly prepare me for the new job and disappear from the planet.  They also promised to find me a job or at least try to before I came to this school, but when I graduated and called back they kept giving me a run around.  Even though I attended school every night, I was unprepared to go into the job market with the Diploma that I received.  Is it true they were teaching a non-supportive curriculum?

What about a class action suit against the DC Government for permitting them to practice or cancellation of this loan?  Thank you.
