Talk to the staff at the refuge - it's what they're there for. Talk to the refuge staff about appointing a solicitor, and how to do that under legal aid now, and stop worrying that he's still saying "jump" and you've stopped saying "how high?" You moved out 3 days ago, and he is freaking out after intimidating you with police witnesses, and almost certainly damaging your car, because you are no longer there to be bullied.
You are still in the mindset that he has power over you. He really doesn't, you know. Yes, he will have contact with dd in time, but that is down to a court to manage, not him to decide. He has no control over you and no automatic right to your prompt attention. You are an excellent carer of your child and have shown that, first by seeking to establish good contact and then by trying to take steps to ensure contact is safe. He has shown the reverse, time and time again. He can't remove your daughter from your care, he can't give you any less money for her maintenance than the zero he's already providing, and he can't attack, scare, bully or steal from you anymore either. This is going to make him angry, but you're not around for him to take that anger out on. You're safe and sound in a refuge.
Talk to the staff and get their guidance on what to do next. This isn't the first and certainly won't be the last time someone in their care is facing this situation, and they'll know how best to handle it - and him. For now, just put it out of your mind and try to relax. He can't hurt you anymore.
