I hate hotels that don't pick up their calls..

I don't understand hotels that don't pick up their calls. I called 2 hotels today repeatedly and they didn't pick up at all! These were 4 or 5 star hotels at that! I thought maybe I got their numbers wrong and double checked online. It turns out countless sites listed the same numbers promoting this and that and I don't really see the point of that if we can't even get them to take advantage of all those wonderful promotions because they can't be bothered to pick up the phone. Unbelievable!
