I receive calls from this number several times per week at varying times during the day. Reverse call look-up indicates the number is coming from Campbell, CA. I don't know anyone or have business relationships with any company from CA.
After weeks of these calls and no one there when I picked up, I finally talked to a person. They said it's from The Campaign Against Immigrants.
She ask if I thought Congress should do more in stopping the innigrants. They ask to send you a envelope to help with the campaign.
