SyncUp Kids Watch Hacked?

Something absolutely strange happened last week with my mom. She received a text message out of the blue by a "woman names Diane" asking if this was Mia? Which mind you is my daughter's name. Of course she didn't answer but it was awfully strange seemingly how my mom is one of my daughters emergency contacts. Shortly after that it kicked her out for the application and she hasn't been able to get in ever since.
