While I believe that you actually did, what you should have done. You also have no idea what upper management has been promising, telling them all along. Do not for a minute believe becouse you are honest, means they were also. Time after time I have seen management string along customers, telling them what they wish to hear, knowing full well, that they can't deliver. They keep them strung along long enough, that the customer has no real other choice in many cases but to go along. It is the way business is done now a days, especially in software.
