I keep getting calls from the number..  but you cannot call it back

This is Verizon Financial Services.

Keep getting calls from this number: They don't bother leaving a message so I don't bother answering or calling back. If your gonna call, leave a F'ing message, otherwise don't bother.

Tru dat home slice

It's Verizon (kind of). When you're a week late on your bill, they start breaking laws and giving your number to fraudulent hacks that would take your money for your bill, but never actually give it to Verizon to have the bill paid.
