Natura Training Institute

I signed up for a Meditation Teacher Training Course thru Natura, and though I enjoyed the course, and upon completion of each exercise, response and confirmation was not consistent. I completed the course a few weeks ago now, and now not a word. The course is no longer accessible to me, I have sent emails, with no response, which makes me wonder if this online facility is even legitimate. I find this very unprofessional. I usually look more into reviews and such (which there weren't any, and at least not negative) before purchasing a course. I'm not one to write a negative review, but hopefully this saves someone else hundreds of dollars! I really hope Natura can pull it together to back their list of classes, I'm sure they have the best of intentions, disappointed is all.
