Hi there, it looks like you cancelled your domain, is that correct?
Canceling a domain after 2 days of purchase means you completely give up ownership of the domain. There is no guarantee the domain will become available to re-register after cancellation.
Since it sounds like you still want to use your domain with Blogspot, I've requested that your domain be restored to your account so you won't lose it.
Once the domain is back on your account, I suggest one of these two options:
1) You are welcome to keep your domain with us, renewing it and and updating its settings to point the domain to Blogspot, by following this guide:
We can assist you in making the necessary changes in your domain manager if you wish.
2) After 60 days from the date of the last registrant contact information change, you may also transfer your domain to another registrar by following this guide:
If you decide you don't want to keep the domain after all, and want to completely cancel your ownership of the domain name, please reply to confirm and I'll be glad to re-cancel it for you.
If you need any help or have any questions, just let me know.
