I receive the same. Several calls a day and when I call the number back I receive a message from Verizon saying the number is disconnected or no longer in service. However I continue to receive calls. Very annoying. Time to stop this!!!
Picked up when this number called, foreign accent on the other end asking for me by last name, Mrs. ....
I just hung up. Seems to be the best thing to do with these types of calls.
