Male calls & leaves no message.

The call I got from this number is where my niece signed up to receive help locating an online school.  It seems obivious they are getting numbers from that type of situation.

now

they called my cell phone this needs to take my number off the calling list. I called the # back and never got to talk to anyone left a message for them to take my number off the calling list and gave the my area code that is what they said they needed to take me off. Don't know it that will work we'll see.

caller is calling and no message , so far 3 times
