Its verizon wireless

ignored...didn't recognized the number.

I called Verizon it is not them.  Verizon states that they only use 800 numbers. The internet claims that they are a telemarketing company in San Clemente, CA. Verizon is currently researching the phone call for me and is getting back to me.  I suggest everyone call Verizon an report the caller.  That way the company will alert users,

Got a call from this same number, but I called back on a land line just in case. Phone message was "this is not a working number."

I got a phone call from this number, they said my verizon account was past due and in danger of being shut off. They offered for me to make a payment over the phone, but I said I would go online and make my payment there. It turns out that the payment due date and amount they gave me was accurate, so it may very well have come from verizon, but I'm still not about to give them a payment over the phone without better verification.
