Brand Name / Business Name Conflict | company using my music without sync license

Quick background on my situation — any input appreciated.

company using my music without sync license. I've been dealing with this for about 12 months now and the situation isn't improving.

This involves content I created over the past 17 months. I do not have documentation proving my ownership and timeline.

What's the typical outcome in situations like this?

I mean following this thread — I could have written this post myself. Same exact problem.
