i agree that it's time to take it to an attorney. likely for 150 dollars max you can get a letter from the lawyer to them if you provide a quick chronological sequence of events from start to present on paper. i'm not a lawyer, but have been involved enough with lawyers/hr folk in issues with people who work for me or my reports to know that:

a) when someone starts putting things on paper, there's a reason.

b) there is also a reason that they pepper with words like "anxiety".

a few bucks now will safeguard you down the road from any potentially more expensive issues.
