Do I have any legal recourse if a Texas state agency claims I threatened to blow up one of their offices when I made no such threat?

A Mr. Cody Bayless, who works for the Health & Human Services office, stated that he engaged in a telephone conversation with his supervisor - a Shantel Hadley. In that conversation she informed him (over the telephone) and presumably via written notice, that I had threatened to murder HHSC employees working at an HHSC regional office in the small town where I live. Over the course of events, I requested that Mr. Cody Bayless provide a written statement whereby he informed me of this accusation. Also, in the letter Mr. Bayless sent to me on October 31, 2023, he did not specify WHY I was forbidden entering the HHSC office located at 204 Riverview Drive, Lampasas, Texas, 76550. So now I am requesting that an official HHSC letter from Shantel Hadley be forwarded to me, stating precisely why I have been forbidden to enter that HHSC office for one year. My requests have been ignored, but I have nevertheless incurred a penalty for it nevertheless. Do I have any recourse?
