My onscreen caller ID is not working (again) (still).

This past weekend I did a chat with "Annie P", and she went through the canned list & rebooted the cable box and satellites, even though I had already done it and told her so.  Then she said she would elevate the issue and someone would call me "within 5 minutes"--which I didn't believe, but was hopeful.  Well, no one called, and here is is several days later and still no call, and no onscreen caller ID.  This problem happened a year ago, and once before that also.  What is the issue?  Can it be fixed?
