Confused about eBay siding with buyer on false claim

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

eBay siding with buyer on false claim. I've been dealing with this for about 2 weeks now and the situation isn't improving.

What are the risks if I pursue this? What's the likely timeline?

This happened to me too. Have you tried filing a complaint with the relevant agency? In my case they investigated and it got resolved without needing a lawyer.
