I haven't heard of any serious hassles from seedsdirect; your money order receipt should come in handy; I know they like proof/ confirmation of orders. I would be clear in what it is you are requesting from them in the body of your e-mail, but you should expect a reasonably fast reply.
If you have a real hard time of it, just report your experience in the seed bank rating site; do a search on our site for the link; I'm too lazy to post the link here
Good luck,
