Don't pay attention to their messages, Keep inquiring them. Go and try with your Representative. They usually are very inefficient. When they sent me the NOA2 It said wait 30 days before sending the first inquiry. As many here in the chat told me email them 2 weeks after you received the NOA2 I emailed them 4 days after the case has not been received by that time, I emailed them 2 days after and finally, they told me that the case was received and gave me the case number. You have to be on top of your case. If you get the representative to send an inquiry they will get on your case. They thousands of cases so they don't mind putting any case on the back burner. You have to be on top of it.
