Loan Officers dragging thier feet

I have had some problems with loan officers not handling thier duties iin a timely manner. Not all of them, but a few transactions that were not handled the way they should be done to get a house closed. I had to move the loan package from one lender because of the most absurd questions and delays. We went to another lender and bam, it was done !! Just needs to have something done to minimize these absurd requiremenst ask by lenders..
