I usually don't pick up when the callerid is just a series of random numbers, but this time I did. It was a survey company doing surveys for ballot measures that may be in an upcoming election. The lady was polite, and I politely declined to participate due to time constraints.
I didn't block them (yet) , but just so everyone knows, its a political survey company.
I have received a call everyday for the past three days from this number. It rings twice then stops. I have never answered it and they never leave a message. The number is disconnected when I try to call back. I have now tried blocking the number.
