Foreign call center. They called for someone I don't know. When I said they had the wrong number, they then asked if I wanted to further my college education. When I said no, they asked if anyone in my house wanted to further their college education. I told them no. Since then, they have called 3 - 4 times a day. They hang up if my machine answers, and when *I* answer, there's nobody on the other line. I re-dialed the number, but got only a few rings and then silence. It's pretty shady and the next time I get someone, I will tell them to remove my number from their list.
