Amazon Refunded Buyer Without My Consent – Now They Likely Have My Item Too. Does Amazon even care about sellers?

Hey everyone,

I sell on Amazon (not FBA), and I recently had a buyer from Italy claim they never received their order. Tracking shows it was delivered, but they insisted it never arrived.

Without my consent, Amazon refunded them immediately—no questions asked. Now I’m out both the product and the money. The buyer likely has both.

Has anyone dealt with this before? Is there anything I can do to challenge this or prevent it from happening again? It feels like Amazon just takes the buyer’s side automatically.

Would appreciate any advice!
