Does financial aid appeal work?

Hi! TAMU is one of the colleges I’d really like to go to, but my problem is money of course. I emailed Aggie one stop about my financial situation but I don’t know if that actually works. The school only gave me $5,500 in loans which is definitely not good enough considering that I’d have to pay around $27k each year.

Has anyone emailed/called them before? If so, has the school given more aid?
