I received their today in California. It sounds like the Verizon's "woman voice". It is a scam. Once they get your billing address ..., better check your credit. The calls that I have received from  Jamaica, would say that they were Fed Ex and needed your address.  This seems like that.

I too just got a call, you in California?  When he said Post Office Validation I said next call was to Post Master, he said no, their mailing.

I gave him my PO Box thank you been verified.

Told him, if I wasn't getting my bills, would I be talking to you now?

I got a call from this # claiming to be Verizon.  I entered the number into a search engin and Verizon does not com up!  Message claimes that my address was  wrong according to the Post Office and asked me to call back with name and correct address.

Who is this
