I'm passing this solution on because it worked to stop calls from 507-983-3137 and 3130. I spoke to this do not call center for a small number of companies that call consumers that satisfied my reluctance by saying these companies want to minimize complaints and save time not calling people who don't want to be called. It's easy, call 307-223-0458, give the caller's phone number to verify the number is on their list and your receiving phone number to remove it from the caller's list and it'll stop the phone calls.

Received a call from 570-983-3137 "Help Dept"..... when prompted for Discount Eligibility, (Press 5) I spoke with a woman requesting my account number from a current Electric bill... She then asked if she could put me On Hold for a minute.... after a couple of minutes, the line went dead. When I called the number back it simply asks whether you want to be removed from their call list.... Smells like a Scam to me!
