my parents refuse to use my correct names and pronouns

I love my parents dearly but i came out about 2 years ago and they still use my deadname+she/her for me. They say they're "working on it" but its been 2 entire years and theres no progress. I understand it takes time to get used to it but by the time its been 2 years???? and they say that me using it/it's pronouns is "dehumanizing" to me and said people will view me as an object. Idk what to do or if i should confront them about it :(
