Get several calls from these phone numbers. There are many people who get these phone calls. But i get a bit sick and tired of these calls. It's going day in and day out. Several calls per day/evening.

Got these calls not only from this phone number but more and ID shows up as different states. Pick up they don't say anything Called back nothing either. Get sick and tired of these calls every day. We got per day like ten calls and don't even care if it's during the day or nights.

These are the different calls they made to my phone:

Washington 206-666-7278
Oregon 503-493-0142
Iowa 712-429-0236
Arizona 623-238-6013
Georgia 678-969-5999

What can I do against these calls???
