Oh grow up, will you. You know as well as I do that neither the company nor the agency will produce anything in writing to anybody outside their respective organisations. That doesn't mean that the course of action is not occurring. To take the view that it isn't happening because I can't produce written proof is so completely naive as to defy description.
It's like saying "please provide written proof that the government is not considering a tax increase". Can't produce it? Ah well, they must be planning a tax rise then! Nothing more than sophistry.
