Hello, I purchased a item that didn't match the description once I received it.The seller agreed to have it back for a full refund but I said I had to open a resolution case to cover myself which they have agreed to.My question is that I have been told by Ebay to send back before 2nd June does that date mean the day I send or the seller receives it ? Also "before" so that means the latest 1st of June or does that include 2nd ? Thanks for any help 👍
