I don't have a Verizon account that can be put in collection and I still get several calls a day from this number.  When I pick up the phone no one is there.

I received several calls a day at all different times.  When I pick up the phone, no one was there.  I finally got fed up and called them back.  They appear to be a debt collection service.  The young lady was very nice.  She asked my name, said that was not the name they were trying to reach so it appeared they had a wrong number, and she would remove my number from their list.
