Hi, thank you for your question. Just a bit more information required to fully assist you:
-How old are the children?
-Which country are they in?
-Is the father named on the birth certificate for them?
-Did you consent to their travel?
Thank you for your question

Having such phone calls is the most distressing experience - and I speak form personal knowledge
Unfortunately the simple answer - no matter how old the children are or where they are - is that there is nothing whatsoever that you can do.
Shouting and swearing at your children whilst on holiday with them is not an offence and is not a safeguarding issue either
Obviously you can continue to reassure and support the children through what is clearly an unpleasant holiday with their father - but trying to contact him about it will not help the children and may make the situation worse
Instead support them on the phone and when they return arrange to discuss matters with your ex using Family Mediation
choosing a mediator trained to work with young people - so that you can discuss future holiday arrangements and ensure this does not happen again
Please ask if you need further details
