No communication from the bank on progress of loan

I app**** for a loan 3 days ago, approved and sent all the required documents plus FICA verification at the branch. When we did the ‘on the phone application’ the consultant advised that it will take 48 hours for the funds to be transferred into my account... well... it’s now more than 72 hours and I haven’t heard a single word from the bank. Not an SMS, email or phone call just to update my impatient self. I tried calling into their loan department and the consultant that took my call said she will send an email to the online team so that they can update me. Been waiting. I need the funds urgently, what is the hold up about?
