Who called from 9492428224

Keeps calling. Wont leave a message. Probably a telemarketer

This number has been calling me none stop since the morning. What the hey? Same thing, won't leave a message so I know it's no one I know.

I called the number back and it is Brandman University.  They call approximately 8-10 times per day and never leave a message.

This number has been calling me all morning today and leaving no messages. But someone posted that its Brandman University who is most likely the caller since I gave them my number a few days ago when they were on my campus for a grad school fair. I've never seen this number till today.

949-242-8224 calls continuously all day.  How can I stop this?
