Website incorrectly marked as phishing and no way of changing rating

Our domain perspectivefunnel.co has been blacklisted by Norton Safe Web for several weeks for "Phishing. We are a website builder (perspective.co), allowing our users to host websites on this domain, none of which engage in "phishing".  We very much would like to have the situation corrected.  Steps taken so far include:

1) Requesting re-evaluation through the Norton Safe Web.

2) Having the site scanned for malware or other problems (it was 100% clean)

3) Creating an account with Norton to register and verify the website. We have uploaded the meta tag, but can't verify the site. No response from Norton on what the issue might be. 

We are at a bit of a loss, and would very much like to get to the bottom of this.  Could anyone suggest what the next steps would be to have this site de-blacklisted.

Thanks in advance!
