Tenant Rights in New York: lease says no pets but ESA rights

I'm in a difficult situation in New York and trying to figure out my next steps.

lease says no pets but ESA rights. I've been dealing with this for about 15 weeks now and the situation isn't improving.

I have been renting for 7 years. My monthly rent is $891. I have a written lease.

Has anyone been through something similar? What worked for you?

Fwiw my neighbor dealt with this and said the lawyer made it go away fast.
