Product ordered 63 days ago, Return processed by customer, Advice ?

Hello there fellow sellers, I handle a small scale Amazon seller account.

Sold a product almost 63 days ago and a return was processed recently. It’s clearly Out of Policy and yet Auto-Authorised.

I reached out to Amazon seller customer service and they said I have to process the return no matter how much time it’s been since the product was ordered.

I sell fashion products, and in my case if I have to process every return that’s months old, this means anyone can just use my product for the time being and just return it after using it by giving any random reason. This does not seem logical nor good for my business.

Any advice on how to handle this situation ? Please do comment if you’ve got any advice or if you’ve been through a similar situation.

Thank you for your time everyone.
