Very rude when told the person they wished to speak to was unavailable.  Hung up without a word.

Robocall and I almost hung up - I should have hung up. A guy gets on the line and with a major attitude asks for our President and says "this is Brian from Tuckers Spinks" or something like that. I just told him I'll see if he's available. I left him on hold and he eventually hung up.

A guy from this number called our office and asked for the president of the company.  I told him he was unavailable but would he like his voicemail?  He hung up without a word.

A "Richard" from "CNA" called and was very rude and demanding. He insisted that he needed to speak with our CEO, and when I asked what it was regarding he said "pre-litigation" and refused to be more specific. When I told him that our CEO was unavailable, he replied with attitude in his voice "YOU said he was in the office!" (Which I did not). And I said that I was sorry but he was in a meeting. The caller was very persistent, obstinate, and RUDE. He eventually hung up.

This guy from "Tucker" calls over and over, and is now getting threatening. Wanted to be our "collector" of debts. Just said he would come by himself to "bitchslap"us. Very unpleasant.
