DMCA Takedown | DMCA takedown on my original content

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

DMCA takedown on my original content. I've been dealing with this for about 13 months now and the situation isn't improving.

This involves software/code I developed over the past 29 months. I do have documentation proving my ownership and timeline.

Do I have a strong case? What should my next steps be?

Have you tried reaching out to your state's bar association? They sometimes have free resources or mediation services.
