Cannot add meta tags into site in order to get authorized/made "safe"

I cannot add the coding into our site template to continue the authorization process (the template does not allow it).

Our site is:

www.theraquatics.com.au

Is there any way that I can move the process along another way; I have been waiting over 3 months for verification (the site is over 4 years old as well).

Thanks for any suggestions in advance. Cheers.
