More information is needed. Mistakes by the Information Officers take place. If you lack written proof of the approval, then your case may still be pending. Perhaps, you were sent a request for additional evidence, but it never arrived to your current residence.
In times of confusion, I strongly recommend hiring an experienced immigration attorney, who knows how to reach a supervisor at the regional processing center. Perhaps, some of the forms needed to secure benefits from an approved I-360 petition were not filed with the proper office.
The above is general information and does not create an attorney client relationship.
Foreign nationals who handle applications with Immigration on their own are limited in the way they can obtain information. As your question demonstrates, you may contact the 1-800 National Service number or you may make an Infopass appointment. Because the information you are receiving is conflicting, I strongly recommend that you either make another Infopass appointment or consult an experienced immigration professional who will help you with your case.
