I just signed up for hosting and my domain registrar is asking for Name Servers.

I am not experienced and if they were mentioned in Hostony's initial email I can not recognize them.

I've sent three emails to support with no answer. Please respond or I will be forced to contact my credit card company and have the charge reversed.

look at your welcome email for something like ns8.hostony.net or ns*.hostony.com
these are nameservers.

If not, just open a trouble ticket at support.hostony.com informing your domain name.

It's the best way of get support.

Or you can provide us with your domain and I'll post the DNS here.
