Asked for the owner and didn't want to leave a message.

-B2B
-Calls our company on a regular basis. Even though my company has asked for me to request to remove the number from their data base.
-Callers ask for multiple people (Execs - Non Mgr Personnel) from multiple departments.
-Every caller, claims to be Mr. Lance Menuey's "Personal assistant."
-When questioned what the call is pertaining, the "personal assistant" is unable to provide that information.
-But they gladly spelled Mr. Menuey's last name. So I am reasonably sure I have it spelled right, according to his "personal assistants."

Mr. Menuey's "personal assistants" call from the following numbers:

720-257-5239 The newest addition it seems. (which means there are likely to be more)

Our office got a call from #720-257-5239 several times saying he needed to speak to the name of my boss and I asked who he was and an Indian accent said (while pressing mute when I spoke so I wouldn't hear the call center noise in the background) "I'm calling from Mr. Rockefeller's office".  Like I'm some dumb [***] American that's going to immediately send him through to my boss because he said that name.  I said no, he called one of my other boss' numbers, he said stop calling and now he waited about 1 month before calling with the same shtick again.  Ridiculous and so annoying.

These are the same idiots who say they are calling from the "office of"  Liz Kelly @ Divergent, Brenda Reimer @ LogRhythm, and a whole lot of other ridiculous and fictitious names.  My favorite so far was from the office of Edward Cullen at CVS Pharmacy!  Or Dr. Smith from New York Hospital!  Really??????  I am one of several switchboard operators for a very large global corporation and I can tell you that as of today, I have logged these idiots as calling from 187 different numbers!  We block as many as possible, but they keep on coming!  I believe they are compiling info to sell.  Beware!  Liars and scammers!

Heavy accent guy asking for the owner I can barely get out more than not available and he said he will call back later and hung up.
