I'm not avoiding giving you an answer to your question, I'm refusing to answer your question. I gave the reason for that refusal in my original comment. That's not good enough for you, for some reason.
And as for my "going to extremes," I simply sitting here typing on my keyboard. Any extremes involved are entirely within the confines of your head. But you already know that.
Your smart ass personal attacks can carry on for as long as your wish. I am a man of unlimited patience when dealing with someone such as you. I would think by now you would have the common sense to ask permission, which is an asinine claim, to identify the firm.
