Update: After going through some old threads, I decided to call the local office and ask for the name and number of the District Manager. The case worker inquired what the issue was, and then spoke with (without putting me on hold so I could hear the conversation) the one I spoke with 3 weeks ago and hasn't been returning my calls.

I'm supposed to check back next Thursday.

Hopefully, this will be enough to stop being ignored.

If not, I'll check to see what my attorney would charge and start the process of getting help, yet again, from my U.S. Senator.

THANKS for the help!
