Only got 1 month of Apple Music trial while im a student

Hello everyone. I’ve read multiple articles about 3 month trial of Apple Music and even up to 6 for students (i signed up and verified my University at Unidays). Anyway somehow i got only 1 month free trial. I took the offer thinking that i will get rest of free trial later or something. Is there anything i can do about it now? Thanks in advance :(
