Sorry to hear you are having these types of problems. I am sure you have been very patient only to get this far and still have delays.
I am afraid that you need to get your information from your Realtor. The rest of us would be overstepping our bounds by giving advice to another Realtors client. Especially since we don't know the whole exact story because we were not involved. Your agent and their broker should be able to advise you.
Maybe a lender will see your question and be able to advise you.
