I can't seem to remove addon domains from my account. I get the following message:

Addon Domain Maintenance

Addon Domain Addition
The subdomain, lutkus.net.donlutkus.com has been removed. Sorry, you do not control the domain lutkus.net!

What's up? Why don't I control the domain name?

Please look into it.

Thanks,
Don
