Comments regarding VermiTechnology Unlimited

I'm interested in using worms for soil building as well as vermicomposting, and I was thrilled to find the wide variety of worms on this company's website. I was prepared to place large orders, and emailed the company *twice* to inquire about the availability of some of their stock (as indicated on their website) with nary a response. I'm exceedingly disappointed not only that they're completely unresponsive, but also that I haven't found another company online with the variety of worms these folks claim to have.
