Same thing happened to me with the "Sam Newberg". not sure what the whole thing was about and when i called the number back i had to listen to an automated voice saying something along the lines of this: "Thanks for calling the number back. If you don't want to hear about any special promotional offers then press 1 now and you will be erased from the call list. Please allow 72 hours to be removed. Thank you." That was the only option as well just press 1 or hand up.... Very weird in my opinion.
