Who called from 3216147968

I get calls several times a day from this phone number and they always hang up. I tried to call them back and the mailbox says it's full!! This is really getting annoying. How do I stop them?

Have been getting messages from this person for since April 27th. They've called me about 5 times. I tried calling back and the mailbox is full. Very annoying.

Sorry, not I didn't mean to write messages. They have never left a message. They have called numerous times but always hang up when I answer.

This number call my phone, does not reply when I answer and has call my phone several times this week.

register with the donotcall.gov and then report the calls. i've been getting calls from this number since apr 26 at the rate of 3 a day.
