psa: landlord keeping entire security deposit

I'm dealing with a situation and need some guidance.

landlord keeping entire security deposit. I've been dealing with this for about 13 months now and the situation isn't improving.

What are my legal options here? Is it worth pursuing?

I've dealt with this before.

I ended up having everything documented, which cost about $3-6 but saved me a lot more in the long run.

Not gonna lie, I put off calling an attorney for weeks. Wish I hadn't waited.
