Not told of the 30 refund policy

In April of 2009 I called and signed up for a real estate saleperson course with customer service. At that time I was not told nor did I receive via email notification that there was a 30 day refund policy. I started the course and answered a few questions. This is a course you take at your leisure, well that is what I was told by the customer service. I found out later when I called that I had only one year to finish the course. A week into the course I found out that I could not make over a certain amount of money due to the fact that I was on disability. I stop taking the course and did nothing in the way of contacting the school, not knowing I had an option. A month ago my sister stated that she wanted to go to real estate school and that's when I called the school to ask them if they can switch names due to my inability to took the course. At that time I was told that I had 30 days to get a refund and I should have gotten that written policy when I signed up on the Internet. This is when it got confusing. I told them I did not sign up on the Internet I called and customer service took my credit card over the phone and I was not informed of the 30 refund policy nor did I receive an email stating that fact. They refused to switch the names or give me a refund. Not a fair school to do business with. Just plain greedy!
