how to block another iphone user via imessage?
I'm trying to block another fellow iPhone user via imessage. I already blocked "imessage" but they're STILL able to contact me? I've had their number blocked via Verizon but that hasn't helped either. I've heard something about changing my "apple id" but I don't know how to do this.
How do i block this person? Please help.
iPhone 4S, iOS 6
