I read on another post here that scholarships and financial aid are technically considered income, so if you call back, I would tell them that. Also, if they at one time put your application in the approved stage and withdrew your money from your account, that is definitely something to argue. They can't take the money and not give you the card in exchange. I would call back and ask for a supervisor again, hopefully you'll get a different one. And if that doesn't work, I would ask to speak to the EO.
