Removing new mobile number from someone else's iMessage account

My daughter got a new Samsung phone recently and found she didn't get responses from her friends who had iPhones. But these friends said they got responses to their responses from someone they didn't know. I did some research and discovered that iMessage sends messages over the internet and not SMS.

We have a friend with an iPhone and when she sent a message, at first we didn't get it, but then when it was sent via SMS, we got it fine.

I sent an iMessage to the person with the old number giving some instructions but haven't gotten a response. Perhaps they're either unwilling or unable to do it themselves.

Is there any recourse for us to disconnect my daughter's new phone number from this iMessage account?

Thanks.
