Just email Afternic and they will solve it out.
It happens to me, but different story.
I have never regged or tried Afternic until one day I received an email to inform me that I have received a $200 offer on one of my .info. It also says if I sell this name through AfterNic, I could get a free seller account which worths $19.5.
Of cause, I accepted this offer and completed the deal, get $140 (high escrow cost) in my pocket and got one year seller account for free. I have tried to sell this name for low $xx here, even no offer.
I don't know why my domain is still listed on AfterNic, but it must be the ex-owner did this(he is also a NPer here, thank you

), and the email sent to the address in current whois record, thats me.
