Unprofessional, unwilling to help with a course enrolled

I have app**** for two courses, they placed me on physical classes, have explained to Carlos or Santo whoever he is that I chose distance learning due to work. May he change to distance learning, he was not willing to listen or understand nor helping. I asked 100times can we get a solution and not go back n forth, that fell on deaf ear. I asked for a refund and he refused. He was unprofessional, unwilling to listen, help. I asked him numerous times to change me to distance learning he kept talking about the system doesn't make mistakes
