7） You will now hear the status of your case. At this point, hit 3 to "
Report a problem". You will hear 4 options. Option # 3 is "If your case is
outside the processing time..." and # 4 is for "If you have filed several
cases and haven’t received a decision on...." You may pick # 3. Previously
there was a trick to hit # 4 and you would be connected to an IO, but I didn
’t have such luck.
