Comerica bank Unathorized transactions(Stole my entire financial aid refund) Florida Internet

I was issued a paychek plus debit mastercard  from the oregon health plan so that they could deposit reimbursement funds. I ended up using the same card to receive my financial aid student grants and loans, which I am now discovering to be an astrological error on my behalf. Not even two days after the funds were deposited into my account I received a voice message saying that my account may 'possibly' be compromised and locked and gave me a phone number to call with a claim number. I call the number which ended up being an automated answering service  which didn't even request me to confirm my identity, or available balance, the operator asked me to confirm whether or not I had made the 3 transactions that they flagged as suspicious, which I did because indeed those 3 purchase were legitimate and made by myself . After doing so it said that my account was clear and in good standing. Long story my entire account was drained in two transactions. one for 954 $ and the second one to a different name for the remaining $932. It is an utter nightmare trying to deal with these clowns. After they transferred me 4 different times, I was told that they would fax me an official dispute form within 4 hours, and if I filed the dispute then they would reimburse my funds on a new debit. Basically, I keep getting the run around I never received the fax and each time I call to check the status I get a different story every single time.....I am so screwed, How are these lowlife crooks still up and operating? I don't know what to do from here, if anyone has any advice I would very much appreciate it because my entire college career is jeopardized and hanging on whether or not i get those funds back
