Who called from 7405982145

They wanted to futher my education.   Didn't get the name.

Just received phone call on my cell.  They didn't leave a message.  Am getting a lot of calls that I don't recognize the number.

Somehow got my sister's number and claimed that I recently filled out a form and gave that number.  Hung up on me when i asked for there address.

Just received a call from this number hung up as soon as I said hello calls from the number about 10x a day

Received call at 11:42am and again at 5:18.  Showed from Brilliant, Ohio...didn't answer as I didn't recognize the number.  Have received 6 calls like this already today, and would like to know why we bother to be on the so called "Do not Call" list.
