I was told on the voicemail that this number is for a verizon bill that was returned to them and to call 800-837-4966. Interesting since we just moved next door and verizon has had our new address for the last month. In fact I have received a bill from them already so I dont know why one would have been returned. Even more interesting that earlier posts say that the number is for Verizon AND AT&T. . .
