Can't verify my website in Norton Safe Web

I'm trying to verify my website (https://www.unlockbase.com) in Norton Web Safe, but it fails no matter what.

I've managed to upload the verification HTML file at the root of the domain but when I click verify, it fails
Here is the file: https://www.unlockbase.com/nortonsw_37b98660-2c91-0.html

 

I also add in <head> the meta <meta name="norton-safeweb-site-verification" content="as3flvw06r1arjdpeih2pkr-h5gzknzxuzl9nilgei76fw0ysn7i03n-2rimkd9j1hujpt8mugzv57ee-5liqlp7ekkwpn-9z-4my3tkx3fep3k6qnppdf9vnv53k2eq" />

My CTO wait 30 days and "Submit Feedback" and get not answer, I can't believe him so I opened my account (info@mwwm.com) to do it on my own.
But I have the same problem, I also press "Submit Feeback" but I just can't wait for ever.

This is specially frustrating since our site is tagged as "Unsafe" for Norton and need to be scanned again after we removed a old file (2008) from our Blog triggering this alert. 

We are also Norton Trust Seal (Norton Secured) customer:

Thanks in advance for your support in this matter.
