Here are some options:
1. Put up with it.
2. Discontinue your phone service
3. Invest in a call blocking device.
Number 3 will finally give you some peace and quiet. Good luck.
I work for a company with multiple locations. This # (971-256-0732) has called multiple times, but when the line is answered there is just silence, and then disconnection. We are very busy, so this kind of call is annoying at best and absurd at worst.
Been receiving calls from this number for several evenings. No one is ever in the blind. Tonight they called about 6 times in the course of about 5 minutes. Blocking them now!
