Where to report errors in the Japan Reference Section?

I would like to report some errors that I found in one section of the Japan Reference Section of this website
Japanese culture, language, history, and travel

I tried sending an email to the contact us link at;
Contact us

and sent an email to beta@jref.meta4-group.com
but got this response,

Dear Sir,
It seems that we never talk about this kind of thing on our website.
Could you please contact with the right target jref.com you intended
for? We are Jref. com friends which is a dating website.
Thank you.
Regards,
Worldfriends Networks Customer Service

Kind of hard to know who is whom here and I would appreciate someone's help in giving me a link or email address that I can contact the administrators about the errors I found. Thank you ahead of time for your assistance.

If you had read a bit further on that page you would have found a link to this contact form:

Thank you, I missed it.
