Last time I bought an EV cert, Comodo wanted a certification from a Chartered Accountant. Aside from the confusion associated with Comodo wanting a letter "your CA", we then had them Google for "accountants in Sydney" and complain they weren't listed on the front page.
"Kindly address the search page to show them on the page in order for us to process the order".
It took hours of complaints and escalations before they agreed to proceed, at which point they wanted to call the company's "public" phone number. Now they could have gone to the company's website, or the White Pages, but no, they found some .ru website with an "accountant review" and called the number listed there. Instead of asking what official phone listings Australians use, the only thing they would accept is "kindly update the website".
Yes, this is probably one of the more incredible examples, but the point is, who wants to risk even possibly dealing with this, when you can have a DV certificate in two minutes and it "just works"?
