Non-federal student loan Dealing with my lender or servicer Don't agree with fees charged Florida

I attended - University in - Florida. They called me several times and pursued me to attend classes. I believe they preyed upon a person who did not know what to do.

I believe this University is a scam and is overcharging students while engaging in predatory practices to get them to enroll. please help.
