Hey, Dish: Zero is not Ten!

I feel sorry for the Dish technician who is getting totally screwed by bad design in this satisfaction survey.  Check it out: you call a phone number to rate the technician on his service on a scale of 1 to 10.  But to rate him a 10, you have to press zero; if you press 1-0 (sometimes also known as "ten"), it will only register the 1.  That means that if you're trying to give him the best score possible, but don't pay attention to the special rules of the Dish universe, you'll inadvertently give him the worst score possible.  The poor guy!  To solve this problem, why not have the ratings go from 1 to 5?  Or even 1 to 9?  Or 1 to any number but 10?  And in the meantime, where can I find a survey for my (dis-)satisfaction about the design of this survey?
