Failed domain registry

I sent an E-mail but a coleague advised me to post here as well. I tried to register a domain with the username brelkoff but decided to change what plan I was going with and the information verification page. After taking the “change plan” link the domain showed as already taken. It shows as still available elsewhere. I hope that this is just a fluke and would appreciate any help. I can be E-mailed at dan(at) Thank you for your time.
