If you have accidentally listed your domain for auction or let it expire and therefore drop from your account, there is no action Sav can take to recover it.
However, there are a few steps you can take to attempt to recover your lost domain:
1. See if the domain is for sale on Sav. If you find it, buy it back.
2. If it is not for sale, contact a broker to negotiate purchasing it from its current owner.
3. If you are unable to recover your domain, try placing a backorder for it in case it drops in the future.
Avoid this problem in the future by renewing your domain.
