calling and swearing and harassing me!

It's a girl; left her a voice message asking her to join us online and clear it up.

This person texts my daughter constantly. they say there name is will, but he wont talk on the phone with anyone. Now a girl from this number is talking on the phone with my daughter. Until i just blocked it.  I thikn it is a girl impersonating a guy.  This is an At&t cell number, although there are numbers in parkersburg with the same exchange.  would really like to know the true identity.
