Loan declined after signing the contract

I went to the branch today to apply for a loan which was pre approved online and at the branch. I signed the contract and was told that the funds will be transferred within 24 to 48 hours. An hour later I was asked to go back for finger prints which I did. My loan was resubmitted and communication was that I might get the loan same day. I received a call a few minutes after and was told my application was declined and the consultant did not know why. This is so painful as I needed the money for an urgent matter.
