Who called from 2143804500

Has called a few times, left no message - getting annoying!

Calls and leaves no message..now on my block list!

I get a minimum of 5 calls per day in my showroom.  The phone rings, no one is there and when I re-dail the number it says "this number is not in service.  Please re-check the number."
This particular number says "Plano, Texas."

called twice and hung up did not answer on return
