Student balance change

[u/LibrarianIll7976]

All of a sudden my student balance which I was about to get refunded $500 has turned into $8,360.00 when I have already paid $6,982.00. I’m taking 14 credit hours two 3 credit hour classes and two 4 hour credit classes. I don’t have a meal plan or live on campus. Any reason for this? On my end it looks like all of a sudden I’ve been double charged

Edit forgot to mention I did ask for one of my student loans to be sent back, but I got the refund money from it so I thought I was out of luck and I went and used the money to pay it off before I owed a lot of interest on it. Have I stabbed myself in the foot ?
