I recently purchased 2 ccTLD domains names. I got the receipts and the domains were confirmed in my account. Four days later, they were removed from the account. According to tech supports, the sales team went through my account and deemed the 2 domains were premium and took them back. This was not system error.
From my past experience, when I click "complete purchase", I would get a message on the receipt page saying "some domains were removed from your cart because they weren't available for sale." This is perfectly fine with me as I didn't pay for the domain.
My question is, can domains be taken back after they are sold?
