It's a scam. Number called me every day multiple times a day. I google every number I don't know calling me and thanks to other people's reports I found out it was a scam. I finally answered because I wanted to tell this person I know what they're trying to do. She could barely say her sentences without messing up. I told her I knew it was a scam and she said that google says a lot of things. I laughed and said I'd call Verizon myself. She gave me the 866 number. I don't have a past due balance. It's a scam. Please don't fall for it
