Can't verify website

I need help manually verifying and re-scanning my client's website http://tascoair.com. I submitted a ticket to support in July 2016 because the system couldn't read the meta tag. The tech logged into my computer, recreated the steps, and couldn't get the site verified. She submitted the issue to "higher support" in July. My client contacted me this week and the issue had not been resolved. Again I got on chat and another case was submitted up. I've read through he threads. This can be solved manually. Please help.
