To a 14 year old, a 9 year old who didn't want to leave mum - what do they care? They just know that the system, the police, their father has forced them to do something they didn't want to do.
They don't care who is in the right. They don't care about anything but the fact that they want to be with their mum and their father has destroyed that - whether that is true or not, that is how they will see it. How can they be expected to have a relationship with their father with that hanging over their heads?
There is money from the father for the mother so she can follow them home. She is, so far, refusing to do so Where does it say that?
The great aunt said the girls' father had turned his village against the mother
Sounds pretty horrible and very likely to me. We don't know where in Italy the father is from. Having spent some time travelling there I can see how this would happen - some of the villages are extremely insular, and horribly backwards to western standards (think women being possessions of men, grandmothers/mothers running the families and DILs being expected to wait on their MILs hand and foot). Remember abuse doesn't have to mean physical beatings etc and the law courts are full of older, more 'traditional' men. If it is one of those type of villages that the girls are going to they are going to be treated as second class citizens from the word go.
