It happens with me at shopee as well. We cancel parcel after the expected delivery date. Got our money refund, few days later the item arrived.

It was some rm 15 cat food, I just keep it instead of the hassle.

True, the honest thing to do is, talk to seller ask them to arrange to collect via courier, or they pay u the courier fee to ship back to them.

I'm sure shopee will get involve between courier and seller, either side will have to compensate for the lost.

My friend was a shopee seller, there was once a parcel sent to east Malaysia, shopee got involved, force the courier find back parcel or pay the insure amount.
