Woman asked to speak with the person in charge of safety (not security).  My directories are by last name only, so she provided three names who she allegedly contacted years ago but who have nothing to do with the subject.  Then she wanted to speak with any one of them anyway, believing they were in Human Resources, but they weren't.  She gave up and didn't even say good-bye, just hung up.

Guy called from this number asking for HR. I told him the directory doesn't have departments, and asked for the reason for his call. He said thanks and hung up. Suspicious.

Company is ISHN, selling CLMI Safety Training.

Called again asking for the Health/Human Services department. I told him that I don't have departments in the directory, and asked about the reason for his call. He said 'thank you' and hung up.
