It's a scammer pretending to be Verizon. They called and did not leave a message. Instead they sent a text message that said call an 800 number by the end of the day or go to www.vzw.
Received a voice mail from an automated machine stating that something had changed with my account which requires immediate attention and to have <MY NAME> contact them 8774030835 and I would be prompted to input my reference number <MY PHONE #>
I contacted Verizon by dialing 611 on my cell phone and questioned them. They said to disregard because they have not contacted me since they sent an email near the beginning of the month.
