I can't believe eBay siding with buyer on false claim is even legal

I've been trying to resolve this on my own but I'm stuck.

eBay siding with buyer on false claim. I've been dealing with this for about 8 months now and the situation isn't improving.

The amount being held/disputed is approximately $35,436. I have tried contacting customer support 3 times with no resolution.

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

NAL, but from what I've read, you should send a written demand. That's the general rule anyway, exceptions exist.

Not a lawyer, but I have direct experience with this.

Here's where people usually go wrong is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.
