I took a course with this school and I recently learned that the diploma wasn't worth the paper it was written on. I paid them half of the money,I bottom line i end up owing them $285.00 i stop taking the course, that was in 2006 because I couldn't afford to take the course any more, so now they want to threathen me with letters and sending my name to collection agent. how can I get my money back for a course that isn't recgonize at all. also they never said that when I sign up for the home course, they told me it was accepted everywhere. i could use it to seek a job was i completed the cousre which i did.also there is another school that i also learned that was a scam, Thomas High School 925 Oak Street Scranton, PA 18515
1-800-228-0799 Fax:(570)961-4030 that was in 2002 now they claim to be Penn Foster School they i still own $300.00 more but would settle for $150.00
