Hi. I think you should have submitted the xerox copies of documents rather than the original documents itself. There could be your T.C. which you must have submitted but other than that I don't think there's anything original they take. Now talking about the fees, it depends on the them to give your fees back. There's a date before which if you exit the counseling then you are eligible to get your fees back. If the date has passed already, then you should try contacting the concerned authorities before its too late.

Regards.
