How to complain about abusive woman on the English helpline without using ameli

After registering with ursaaf, I have never received anything from cpam. I have a chronicife threatening illness that requires daily treatment. Instead of just receiving the rights to access care form with a temp soc number, I had made several calls to the usless English helpline. They had me send i documents and said they would expeedite it. It's like I was sending my documents to the fire place. Nobody from alpes maritimes ever even responded. Finally helpline setup an appointment and required all of the documents you need for a permanent social and carte vitale. The same documents I sent I brought with me and they were accepted. Two weeks later I received a letter saying they need a birth certificate. I gave the man at my appointment my official American birth certificate with raised seal. How could they not have it? It was sent multiple times and received in person. When I called to the English helpline, it was the first time I spoke to a nasty woman. Even for identity verification she asked me for my bank account. Who walks around with theirbank info? Usually I have been asked for address or birthday. She was being difficult and abusive. I told her I wanted to know how to file a complaint about the local cpam here in Nice but dont have ameli yet. She said I could tell her but its useless and there is no other way to file a complaint. Thats a lie. This was at 4:30 on March 21st. She needs to be disciplineed or even fired.How do I complain about her? I see there is an ombudsman?
