Discussing about language schools

Hello Everyone I have a trouble with language schools for enrollment
The Thing is i sent email to the schools yet one or two schools can't help me at all because i have hard hearing with 50dbs
They politely decline me but i keep still finding schools that accept me
But language schools have age restrictions i heard
I am 30 years old and want to study in university
I asked these schools
JALs and Kobe international school declined me so
i want to know which schools are friendly and understanding
i will keep finding schools yet i want the advice
i am learning japanese by myself
i will take n5 exam next year
