Called, didn't leave a message.

Has called my phone 6 times in the last 2 days.  It just started 2 days ago.  Doesn't leave a message.  When I try to call the number back it says it has been disconnected.

I have also been getting calls from this number.  They don't leave a message.

Received a call from this number this morning. Left no voicemail & when I called back it said "this Verizon customer is not available" (it was pretty close to saying something like that) when I get a call I o most often put it in contact list even if u title it under things such: don't know, no voicemail etc.

Keeps calling multiple times daily. No message left. On the call block now
