I've been using Vinted for a few months and recently purchased a bundle of six baby items. While really happy with most of the items, one of them didn't look new as it had been described, as it had faint stains of something which didn't come out in the wash. Messaged the seller to find a resolution as I thought a partial refund would be possible. Seller originally requested I send the faulty item back, but this would have cost me more than the item's value so then I requested a cancellation via Vinted with their agreement. However Vinted gave me a whole refund which I felt was a bit unfair on seller, as I had no issue with the other items.
I tried to find a way to make sure seller is not out of pocket, including offering to buy another item at a higher cost on Vinted, or to pay them separately via PayPal. But the seller wants me to return all the items, and does not want to do any further business with me.
I would prefer to keep the items and just want to find a solution with the seller, ideally without getting banned / blocked from Vinted. AIBU / what do I do?
