CSA don’t listen and ignore legal documents

My husband has been informed by CSA that he has a daughter who is now 8?!. He has been raising this child for most of her life until the credit crunched had forced him to seek employment in UK.
When he had arrived to uk – he started working as a housekeeper on low income.
Meanwhile the child was with the grandparents.
The mother of the child who had no contact with her before [and long history of drug abuse and crime] had turned up and abducted the child. funny enough she went after my husband to uk hoping that he gets big $$$$ to blackmail him with the child.
When my husband had discovered this he paid a detective to find the child and succeeded. He managed to get his daughter back but the Ex did not give up as the benefits [that she had started claiming before child’s arrival to uk] demanded a proof of live / residence. She attempted to “snatch” the child with a couple of big men which she had picked up in the night club. Luckily for us the police had got her out from outside of our house. She had admitted to the police officer that that she intend to abduct the child. And we have been put [by the police] on the list of victims of abuse and stalking.
2 days after – we had a letter from the court saying that she has filed for an emergency residential order. The judge didn’t listen to my husband at all and gave the child to my husbands EX.
The judge said that she had spend with her a few days more !!!! how – we don’t know.

I have spend months crying and worrying if she is alive, has food and protection. There’s no love and care in this house and the child has been complaining to us that she is a servant in her mother’s house.
We have informed social services to get to know that the child has nothing to wear because her mother is poor and living on benefits.
and yet she has all the money for drugs and alcohol and none for the child ?!
they have asked her if she drinks and does drugs and surprisingly she said NO – what would they expect she’ll say !!! they have dismissed us saying that the child looks ok, but they haven’t spoken to her.
now when my husband is a manager he had been informed by CSA that he has a daughter for which he is in the areas for payments.
We have sent all of our documents to prove income and were told that the EX said that my hubby has no contact with the child so he will have to pay the full amount of CM.
We have given them a letter from the court stating that we get overnight stay and we are currently fighting through solicitors for contact as the Ex thinks that she can do whatever she wants and we have no rights. CSA had believed her rather than take under consideration legal documents.
We have also informed them about all frauds that she has on her account and yet they have dismissed us saying that “she said”.
Why are we treated like sponsors rather than a family? Why nobody wants to listen to hard working family who is able to provide for a child on the higher standard if life possible.

Now the Ex has broken up few marriages by sleeping with husbands whose wives took revenge – they have informed DWP about fraud that she had committed i.e. living with a partner while claiming to be a single parent, having 2006 reg car although claiming to have no funds for food, doing cash to hand jobs, etc… she had lost her benefits because of that and she is mad.

I fear for the safety of the child as she is clearly not need there anymore. When we had her for a weekend recently I took her to zoo and she loved it – following Wedn I have seen her with a cut nose. I have asked her what happened and she only said that she told her mom that she loves spending time with me and looked down on the floor.
I just don;t know where to seek for help anymore.

If CSA had listened to us in 1st place maybe the EX would discovered that there;s not a lot of money in the pot and it;s time to live it all behind and move on to a new country / man / project etc..

I have got such thoughts that I am loosing my mind and need holidays far away from here to find new balance.
