Why are they calling me and never leave a message?  Do they have the correct number?  Please stop calling!!!

We receive phone calls on a regular basis, sometimes more that once a day, from 442-084-922780 asking for someone who no longer works here. And we repeatedly tell him that the person no longer works here. He does have some kind of an accent and doesn't wait for a response.
He called around 11:45 on Friday May 2.

Calls cell and leaves messages that don't apply to me.

I'm getting the same type of call at my office. They are calling for people that do not even work at our office.  Sounds like they are from India and they get very upset when I tell them whoever they are asking for does not work here, I never answer calls on this number anymore.

He called to speak to someone that works with me, and when I tell him I am not her and she is not here, he starts yelling, "why are you denying that this is you. I know it's you. Well if you are not her then how can I get in contact with her." Before I can say anything, he hangs up.

This number calls my office and never leaves a message or say anything

Calls once a day, in the afternoon.  Never leaves a message. I suspect it's a bill collector with a mask on the true phone number.
