See my comment below. DO NOT CALL THEM BACK. Look up the real Verizon number on your bill and use that instead: these guys are NOT Verizon and if you give them your credit card number they won't just take the 20 bucks or whatever you think you're paying them.
They just called last night. Loud background. I said "hello?" 3 times then a man coughed and said "Heather?". Then he said he was with the Michigan Police Department and was doing a fundraiser and calling for a monetary donation. I promptly hung up on him. Total BS call!!
