How do you get an answer back on a Bank of America HAFA Short Sale?

Someone who knows the ropes, please let me on on the secret of how to get a HAFA approval from Bank of America. I thought I was Bank of America Short Sale savvy until they implemented AMS as their servicer for HAFA Short Sales. I have had a HAFA Short Sale complete with all documentation submitted for almost a month and a half. The BPO is done. I only know that because the agent called me about access to the house. AMS had no record that it had been done. I send regular messages through Equator requesting an update and call AMS every week. Week after week I get the same answer, "the file is in underwriting for review". I found out that that meant the file had been sent back to Bank of America for approval. I have worked with Bank of America and I know how long it takes for them to process a file and send it to their investors for approval. It could be anywhere between 3 - 6 months. Isn't the purpose of HAFA to shorten the process? Someone who knows the ropes, please let me on on the secret of how to get a HAFA approval from Bank of America. I would appreciate it very much. I am ready to tear my hair out. It could be ugly!!!! HELP me spare the hair!
