Who called from 8017704495

I called the number back it said it was an educational institution.  Then it said if you wish to have your phone number removed press 1 Then it asks to put in your 10 digit number then it says it will take 24 hour's to remove your number off their call list.

yea same with me.

Did not sign up for or solicit any calls from this number, caller, or organization

Called this morning - when I answered all I heard was noise like a lot of people talking (phone bank?) no answer, just a hang-up.

Blocked call scam!!!
