How do I document suspicious financial activity?

(reposted from r/financialadvice I didn't realize it was inactive)

I'm a first year university student, starting this upcoming September. I come from a low income but somewhat well off household, so I'm in that sort of middle class range where fasfa gives not a whole bunch but enough. I partially rely on fasfa to pay my tuition and other uni costs, though I have some help from my parents.

Now, with that, initially when I applied to my current university Their upfront cost seemed relatively affordable, hence my decision to apply.

My first issue popped up when, despite the check being mailed at the beginning of July with some scholarships id won, my aid didn't get disbursed till late July early August, and that was after I already emailed my Uni asking where my aid was or when I received it.

I'm currently in an ongoing debacle, where my set price of tuition keeps fluctuating. First, when I checked it was in the mid 4,000 range— unaffordable for me. I emailed the financial aid department since I assumed it was only a clerical error (none of my aid showed in the payment portal). After that was sorted, it was set to around $770 which was feasible. I checked today, and my total payment was bumped up to $1,020.

Now, regarding the title; I'm not sure if anything suspicious is happening. I'm a first gen college student, so I don't know if this is par for the course. So; is it normal that it took so long for my scholarships to be disbursed, and my tuition number to change often? If not, how would I go about documenting what's been going on/determine if anything shady is happening or if it's just my nerves talking?

Thank you for any advice! If more information is needed I can add it to the comments
