Tuesday morning go into your local US Congressional representative's office and ask for someone in constituent services. Bring all of your documentation, including proof of payment and all of your contact information. Even if Congress is on break (okay, they're broken), their staff will be working.
Don't mess around - you're time is limited, make sure your lender is working on the rest of your underwriting conditions.
You can find your representative here:
