I suggest you to visit USDE(UNITED STATES DEPARTMENT of EDUCATION). Actually, they maintain a database, which contains information about all the accredited schools. More over, once you consult them they will tell you how to penalize those DIPLOMA MILLS and will most probably help you in recovering your losses.
I would just build on the discussion made so far about accreditation of schools. Accreditation, in particular the accredited online schools
means that degree you secure would help you apply for any university later on without any fear of being rejected for having an unreliable degree. Very recently, reports came where universities showed reluctance in acknowledging some of the online degrees; but those online schools that had proven accreditation were able to convince universities to accept them as reliable education providers.
