Sorry for your bad experience.
If you have evidence to demonstrate that you have shown up in the day of interview and bring all the evidence and documents to INS local office by making appointment via infopass to ask them to reopen your case. It is obviously not your fault.
The key evidence is the one to prove you showed up in the day of interview.
If your English is not so good, better to hire a good american lawyer to help you. Consult a lawyer first.
Good luck
