Unfortunately, the spelling of a domain can't be changed once it has been registered. You can try to grace delete the domain. Looks like you have a little over 100 hours left to submit a grace deletion request.
How do I submit a grace period deletion request?
Dynadot is one of the few registrars that supports domain tasting also know as grace deletions. Most domain extensions support grace deletions and most give you up to 118 grace hours to submit your grace deletion request.
To submit a grace deletion request, please follow these steps:
Not all domains can be deleted for credit. Check out our grace deletion chart to see which of our domain extensions allow grace deletions and the number of grace hours allotted. Any that cannot be grace deleted are listed as "none" under the "Grace Period" column and will be listed as having 0.00 grace hours left in the "New Domains" section of our control panel after registration.
Even if your domain is eligible for grace deletion and your request is submitted within the grace hours allotted, some domain extensions have a maximum rate of deletion, which limits the number of grace deletions relative to the number of registrations. If we are at the max rate, your request will be put on the wait list. You can see which domain extensions have a max rate, check out their current rate, and see how many requests are on our wait list all on our grace deletion chart.
If your grace deletion request is successful, you will receive a refund in the form of account credit minus any grace deletion fees. Most domain extensions have a fee of $1-$3, though some have no fee and some have higher fee. All fees are listed under the "Deletion Fee" column of our grace deletion chart.
If you would like this account credit reversed and a refund issued to your original payment method instead, please contact Dynadot support as soon as possible. Refunds can be issued within 60 days of the payment date.
