I recently contacted USCIS online to get a e-copy of my Approval notice which was not received by mail a year ago. They responded a month later saying that I need to call their customer service number instead. I call the number and the automated bot just keeps asking me to send request online. I ask her to connect to an agent and she disconnects saying she cannot connect. This is the worst service ever. Either respond online or on phone. Who just disconnects without solving the query?
