Here a copy/paste of a useful comment I saw elsewhere; I'm getting calls from 973-273-78xx (last 2 digits varies). Then I figured out how to stop the phone calls; either call 307-223-0458 or send an email to; give the caller's phone number (to verify the do not call request will be effective) and your receiving phone number (to remove it from the caller's list) and it'll stop the phone calls.
