This phone # has been repeatedly calling me today but does not leave a message.

Same thing, calls but no message

Call back gets "Welcome to the Verizon Wireless Message Retrieval System.  If we called the wrong number, please press * now.  Enter your ten digit reference number."  When I google the first part of the recording, I found several references to it being Verizon Wireless collections.  Posters say they received many calls, no messages but when they call back and put their number in, it's Verizon claiming they owe money.  A couple posters said they don't have Verizon accounts.  If you have a Verizon account you may want to check with them.  If you don't, it's probably an error.

Recorded robotic woman's voice message that said this is an emergency my windows license is expiring and I needed to call some other 800 number. Complete scam, Microsoft does not call to tell when windows license is expired, silly silly scam
