Financial aid help

I got a pell grant for the summer of $3,248 but the school is only wanting to give me 800 and after my class and fees are paid it’s 600 left it says I’m currently ineligible for the remaining money but the whole ass government approved me of that money will I get it later or not at all? I need the money to pay for my entire cosmetology course because I won’t be able to get approved for another financial aid because of my parents income even tho they don’t support me at all
