Onlydomains.com — Domain name registration
They are a scam. If you register a domain and pay for it, you will get a response like this:
Unfortunately the domain name is not available to register. Occasionally our registration system does not correctly detect if a domain name already exists.
In some circumstances, the domain name may appear on a non-published reserved/banned list, and for this reason, it may appear that the domain name is technically available to register. This order has now been cancelled and a credit will be applied to your account.
YOU WILL NEVER GET YOUR CREDIT.
