Every time my son's Verizon bill is due they call my home phone. I ask him if he paid it and he has not...so it IS Verizon. When he pays it, I quit getting the calls. It's never a live person if I answer. It's always a recorded message (with my son's name attached), so I know he hasn't paid his bill.
They say they are Verizon's debt collection group but were unable to transfer me to customer service. I also don't have any outstanding bills with Verizon. Sounds like a scam to me.
SCAM! Says its Verizon calling about past due bill. My bill is never past due because it's on auto-pay with credit card. I've called the real Verizon customer service several times and they've assured me that my bill is not past due.
