Trying to cancel Student-Teacher Edition?

I chatted with an Adobe Customer Service Representative online about two days ago and they kept telling me that I couldn't cancel my account and then they also told me that they could give me next month free, although I don't use creative cloud anymore. I told them no and they told me that the only option that I have is to wait until August to cancel my subscription. I called today and a customer service rep told me the same thing, but he didn't even offer me a free month, he just told me that I have to wait and and that if I cancel it now, i have to pay an extra $19.99. I really just wanna cancel my account now without any fees because I'm tired of my mother yelling at me to try to get a refund and it's really irritating trying to explain to her why I can't because I have to "wait until August".
