It is Verizon looking for a payment

No, it's not Verizon; it's a scammer pretending to be Verizon's debt collector. My bill is autopaid. No way it's late.

Okay sweet now I know it's a scam then. My payments are through a Verizon in Gburg not Springfield.

They left message said to call 800-754-0961about overdue bill. Sounded automated to me.
Curious why they said to use my phone number as a reference number, I do have an account.
The 800 number they say to call is not the same 800 number to use, that's on my bill.
I don't know what's legit anymore. I'm getting so many scam calls. I recognized a number as one that had called before and was a scam, so I answered to tell them i knew it was a scam and to stop calling me. The foreign sounding guy told me "but I want to talk to you mother f***er". I hung up. Also have 2 voicemails from people claiming to be from the IRS and sounding kinda threatening, saying to call them back and to do it before they take further action.
It's like I don't even want to turn my phone on anymore but I have to. I'm on disability and have to have it.

Legit.  I was behind on my Verizon bill.
