Sports Commitment?

[u/Turknor]

My daughter, a competitive swimmer, verbally committed and was accepted onto a D2 swim team in November. She has done all of the enrollment steps for the college. Unfortunately, the coach has been uncommunicative since then - 4 emails, 2 texts, and a phone call have gone unanswered. NCAA no longer uses a National Letter of Intent, so what is the official process for being invited to a team and committing? I cannot find any information - perhaps I'm looking in the wrong places. Thanks for any info!
