I must have contacted them through email at least half a dozen times about 2 iris bulbs that died next to 1 that survived. The first few times they did not respond. They finally did when I expressed my frustration, as their site states they will offer a refund for defective product. They kept telling me to send pictures of the dead ones. Each time I did, they claimed that I still needed to send them the photo. Finally, my email stated that my email service was unable to connect to theirs. They make it impossible to reach them. I couldn't find a phone number either. They are totally careless about their customers.
