New York Life promised me 60% of my income and gave me nothing

I’m working as a manager for H&M in California and I have New York Life because of my company. I got pregnant last year in October and I called New York Life to make a maternity leave claim in match this year. They told me that i would be paid at 60% of my pay and that was it. I called multiple times to make sure I’ll get paid but they always told me that my short disability leave will chick in the day I’ll go into labour and if I want to leave work earlier I should use all my vacay and welness. Big problem the day I went to the hospital I called again and spoke with a manager that told me that thery don’t pay anything because I was supposed to file a claim to state California disability, which they never mentioned before and I couldn’t guess either. At no point since March they didn’t told me about the state CA disability and the steps to follow. Today I’m finding myself alone with a newborn and no money, I didn’t paid my rent, I don’t eat so I can save and feed the baby and I’m stressed because I can lose my apartment. The only thing that they said it’s like they’re sorry about the inconvenience and that I wasn’t informed correctly. That doesn’t help or feed my baby or pay my rent.
