Hello Virk,
As suggested by others, you must first file CAIPS / FOSS or GCMS. you call it by any name. The purpose is to find out the exact reason of denial. Then about your college fee, if you are intending to apply again, then do not withdraw your money as it will lead to some deductions usually around 100 to 200 dollars and also the loss of exchange rate you paid already. Hence do not withdraw. apply for caips and then reapply for visa keeping in view what CAIPS comes out as.
Cheers!
