Betsy,
I'm very shocked and sorry you had a bad experience with NH. I've never ordered from them, but I see high ratings.
All is not lost yet. I would pot them all up or put in very good soil. If there are any good leaves I'd cut off half of the bad ones. If they don't respond in a couple days, call or send another email.
For that $$, if you are not really satisfied, DEFINITELY give them a bad rating on Watchdog. I'll bet they respond. There is a Vendor rating on Gardenweb too.
It's easy to say, but try to not get too distraught, something, somehow will work out. Been there, done that.
Not much help, but if they have good roots, with a little TLC, they will probably be very nice next year. Still no excuse for sending those plants.
