I agree with the prior answer. HIPAA applies to health care entities not funeral homes.

Much depends on the extent of your injuries and treatment if any. If none, you have a customer service issue only.

What can you do? Block the number. You may also want to look on website of your local courthouse to see if there are, in fact, any complaints filed.

Often times asking your US senator or US congressperson to inquire on your behalf brings results.

It is not uncommon to request a mental status exam even when the alleged impairments are primarily physical.

This is a legal Q&A board rather than a job posting site. If you repost with additional details perhaps the lawyers here can provide some guidance.

HIPAA only applies to health care entities.

No. As an at will employee you can be fired for any reason or no reason at all with the exception of certain Constitutionally protected matters.

In my opinion, there is no "reasonable expectation of privacy" for anything visible from the street.
