CSA is a joke and causes psychological stress

3 years of trying to get CSA to fairly assess my claim ended up in HMCTS for review this November but CSA trying to close vase due to them suggesting I no longer as birth mother am primary carer. Family Court mistakes awarded lions share if child contact with ex (abusive) partner but they are failing to acknowledge the new law of shared care. System is a joke and psychological abuse to me as birth mother.
