I just had this happen, I can give you the full scoop because I was getting ready to do a post.
I registered a domain name, it sold 6 days later. The buyer contacted on DAN first, $500 offer but while I was looking at that and starting to research buyer.
Email sold at Afternic, actually GoDaddy registration path.
They tell me to unlock he wants to transfer it's at NameSilo, he wants GoDaddy.
I tell them it new, they say we will ask him if he will accept a push, if not we will contact you in 55 days.
I said I am not waiting forever, 5 days later they are like buyer did not reply.
I am thinking you should accept push, wait and then fulfill your other customer in this transaction.
I said let me clear not waiting 55 days, the rep cancelled the transaction, refunded buyer. told me my account was suspended. I said you just committed fraud saying you cancelled and reason could not verify the owner.
Contacted Paul Nicks, he had the suspension removed immediately. Said they should have done better.
I go back to DAN figuring it was the same buyer, he said I purchased yes it's in transit, he had no idea. I explained to him NameSilo free account, free push. A month later he says sorry for delay getting back got money thank you, and I no longer interested in the name.
