This guy called me 9am on Saturday. He told me it's a survey for continuing education. He asked me some questions such as when did I graduated from high school and college, If I'm US citizen, when I'm planning to go back to school...he confirmed my email, my zip code and phone number. When he asked what my home address is, I refused to tell him. I asked him why he wanted my home address, he said he can find a school near me, I told him to use the zip code. He hang up on me immediately.
