Purchases at GoDaddy Closeout can still be taken back

Yesterday I picked up several domains at Godaddy Closeout followed by email confirmation of the purchase. Today I happened to look at the order history and found two refunds (no email notification of the refunds nor explanation). I called the support and the guy did some work and then told me that the domains were listed from enom and the registrants decided to renew (even after the domains landed in Closeout). So, be aware that your purchase (even with receipt) may not certain.
