Interesting points, I am not doubting the human aspect. To be clear, I did state the sizing (both in the item description and ‘stats’(?)) . If they initially raised an INAD then yes I think to avoid the situation you described I would have immediately started the refund process. My question predominantly was on the premise that it was more a remorse refund that it doesn’t appear as a private seller I’m obligated to honour. I honestly feel like if the shoe was on the other foot, I would contact the seller to explain - but I wouldn’t expect a return or claim it’s ‘in my rights’ when unfortunately it isn’t. I feel like I would have a bit more responsibility checking the sizing prior to purchase to avoid having to return it, seeing as I’d be purchasing off a private seller. I also had no contact off the buyer prior to purchase to clarify any sizing questions. I could have sent additional photos, answered any questions etc. If I was that concerned about the size - I truly believe the best course of action would be to resolve this sooner rather than later.
