There have been a LOT of issues in a LOT of areas in eBay for the past two days

The seller cannot close their own account so soon after a sale, so whoever it was that suggested that obviously does not know eBay basics. eBat *may* have closed the account if they are a scammer, but that is doubtful since eBay support scammer sellers

Did you buy on this account or as a guest?

Have you changed the date in the drop down menu in your purchase history?

What was the item number?
