Don't you know? ... "Political Surveys" are exempt from the DNC list!
ANYONE can call your number by just saying they want you to answer a few of their survey questions first. THEN they ask for your credit card numbers and any other information they can con you into giving them.
Called my cell. I did not answer. They did not leave a message.
If everyone who is outraged by this would not do business with these people, not participate in their "surveys" or whatever crap they want from you and perhaps waste THEIR time, this would stop. If I have time and need amusement I have answered these calls and pretended not to understand what they are saying. I usually stay on the phone until they hang up in frustration.
