Bank of America's Equator

Is Bank of America's Equator system working properly? What can I do when it doesn't?

I had was doing a short sale on my investment property in Las Vegas via the Equator system with BOA since 1/10. The agent received the approval letter for short sale on 6/1 but was allowed only 5 days to close. The title company couldn't do it in such a short notice so we missed the deadline. I emailed the bank's vice president and asked for an extension to close the escrow. On 6/4 I received a letter from the negotiator saying the short sale was declined by Fanni Mae, and they may reconsider the short sale if the buyer can increase the offer price or the home owner can make a cash contribution. On 6/7 I was contacted by the Client Relationship Advocacy department of the president's office. I was told that the foreclosure sale date was postponed to 6/21 and that I have to fax them the listing and purchase agreement, required financial docs to their office. Then they will assign a senior negotiator and the short sale will not be done via the Equator System. And that 5 days before the foreclosure sale day I should call and request to postpone the date. But the buyer walked. Starting on 6/14 I had been calling CRA dept multiple times to extend the foreclosure date. Their associates left the advocate in charge the messages, but she never got back to me. On 6/17 we received a new offer and the agent faxed the offer and the docs to the CRA dept. When I called again on 6/21 their associate relayed to me a message from the advocate that she's aware of the foreclosure date and needed time to work on it. On 6/22 the advocate finally returned my calls and said the house did go into auction and was sold because we didn't initiate the short sale via the Equator System. I was really upset and frustrated with the whole situation. I put in a lot of energy and time to try to avoid foreclosure. Since then I have been looking into filing personal bankruptcy to protect the $200k equity on my primary residence in Seattle. WA state allows homestead exemption $125k. What are the chances of the bank serving me a deficiency judgment? Can I still unwind the foreclosure? Can this be a wrongful foreclosure? Is there anything else I can do at this point. Thank you very much for your help in advance.
