Who called from 4256897000

Calls a couple times a day. If we answer, there is nobody there.

CALL from this # to my cell. Asked for a relative who does not live here. when I told them that and asked who they were they hung up.

Asked for me by my former name (hasn't been my last name for 15yrs). Stating they wanted my "professional opinion" about Washington issues as a registered voter. Then asked for my birthdate. Nope nope nope.

Caller ID said "Research Center" so I just let it ring off the hook.
Now BLOCKED.
