Hypothetical question

Looking for advice on a legal issue. Here's what happened.

DMCA takedown on my original content. I've been dealing with this for about 6 months now and the situation isn't improving.

This involves content I created over the past 22 months. I do have documentation proving my ownership and timeline.

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