discount hydroponics

Well I recieved my order this morning from Discount Hydroponics. As i'm going through everything I notice they didn't send my rockwool cubes (which they charged me for), and my bag of perlite has a baseball sized hole in it with a little piece of tape on the bag in a sorry attempt to patch it.

Have you contacted them and given them a chance to make it right?

Yeah, I left them a message. On the packing list every item had a hand written check mark, even the rockwool cubes. That sucks, I have seeds germinating ready to go in the rockwool, but I have none. I guess I'm about to start searching for rockwool alternatives. Does anybody know of some kind of do it yourself thing to start the seeds off in my bubbler? Or how to do it without rockwool? I have some perlite and vermiculite laying around if I could manage to transplant from soil to hydroton
