Apple music student subscription is not getting along with unidays

I submitted my data to myunidays, and they told me that I am approved to use student plan in apple music, but my college is not supported by apple music, I tried to add it via sheerID, but they told me something like "your college is not worthy of this subscription", what do I have to do in order to activate student plan in apple music? I want to spend 3$ instead of 5.49$ :(
