It is verizon. I forgot to pay my bill last month - they sent me a text and so I made the payment. Now they're calling. No message but I did call the number back. The fiber networks are usually owned by one company and another company pays to use them, so it might not show that it was from Verizon. I doubt verizon owns all their own fiber network.

called my cell phone. left no message.

Not necessarily, unless Verizon uses somebody else's lines!

Level 3 Communications - Possible Skype, Vonage, Ring Central Or Other Voip Phone

It's definitely Verizon Wireless customer service..

Keeps calling, doesn't leave a message. The number calls at odd hours: 5am, 3:30am. Regardless of what nmk815 said, it is NOT Verizon Wireless! Another search shows it's a VoIP from Aurora, IL.

It is Verizon Wireless telling you that you account hasn't been paid and they are going to shut off service if you don't pay.

she said I won 50 million dollars and get to meet mindless behavior. She said her name was malinda brace.

called, did not leave a msg

Just received a call.  I did not answer.  They've been calling several times this week.  No message (of course).

Very unprofessional to call an unknown business not identify yourself and /or business and not leave a message regarding the nature of the call. I dont do business that way and have no respect or time for those who do.

This number keeps calling and doesn't say anything or has some recording about which service I have, if its Verizon or not. Its annoying and alarming.

It's Verizon Wireless CS.

Me as well. Twice!

Called my mobile. Didn't leave a message

Called me today and last week twice. No message left.
