Who called from 3102098311

They called 5 times in 5 days.  No message.  I called back and it said Education Information Center.  Who is this?  What do they want??

Called several times with no message. I called back, got a recording stating "Education Information Center, press 1 to be put on do not call list".

I pressed 1, it said I have been placed on the do not call. I did a survey online several days ago concerning education, these two could be connected.

I asked the location of where this caller was located and there was not a valid response.  Untrustworthy.

Called three times and left no message.

call several times per day leaving no message ....called the number myself  and was told to dial 1 to be added to the do not call list .... did that ....I still wanna know who and why ....
