This number calls me at least twice a day and it's some foreign guys always asking for a different person.

Some foreign guy keeps calling me from this number. He won't identify himself and when u call the number back it is a non working number,

Plus he doesn't leave a message when it goes to voice mail

This number calls my phone at least 3 or 4 times a day. I told them to stop
