Lease Issue | rent increase above legal limit

Real talk: i've been trying to resolve this on my own but I'm stuck.

rent increase above legal limit. I've been dealing with this for about 8 weeks now and the situation isn't improving.

I have been in this property for 8 years. My monthly rent is $2,816. I have a written lease.

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

NAL, but from what I've read, you should document everything. Of course teh details matter a lot here.
