Help - Unable to verify site after adding meta tag & HTML page

The website that I developed has been flagged by Norton as having an 'annoyance factor', I added the meta tag and the additional HTML page to my site here www.theoldchurch.co.nz(link is external) but when I try and verify in the console it does not work? My site is still 'ownership not verified' and I have not heard anything back after 'submitting feedback' several times.

Can anyone help?
