I think you might be confused. Ebay gave me a full refund and I can keep it.
the progress was thus
I bought the item
It arrived
I saw it was mislabeled
I reached out to the seller
The conversation led nowhere
I asked ebay to step in
Ebay reached out to seller, giving them 5 days to send me a return shipping method
they chose not to
I got a full refund
It seems like you are under the impression that ebay sided with him, which they didn’t. The incident is fully resolved now.
