If you followed the following option sequence:
Call 1-800-375-5283
Press 1->2->2->6->1
Enter your receipt number
press 1 (now listen to the case update info....)
press 3
press 4
before you reached the IO, were you asked to wait on the line and did you get to listen to the standard NSC hold music/message until your call was connected?
Thanks a million.
