I had someone win an auction on eBay for my Saskia tonight. They have since sent me 4 messages claiming they have paid and demanding that I send the baby, even though there is no payment showing up on eBay or in PayPal. They are even calling me a bad person for telling them I won’t ship until I have the payment. I responded to the first 2 messages but not the last 2. I suspected they wouldn’t pay, since it was a brand new account opened just today, and I know they have no intention of paying, so I want to cancel the order and block them. However, I have to give a reason for canceling, and the only options are I’m out of stock, the buyer requested the cancelation, or there’s a problem with the buyers address. None of those apply. Also, how do I block this person on eBay?
