One huge mega mess. I ordered some bottles which, according to their site were in stock. Two day later they send an email stating that the bottles were on back order for at least another month. I asked to cancel my order, only to receive a canned apology email. Now, more than a month later I received two emails in one day. One stating that my order was cancelled and the second one stating that it was shipped. Seriously, how can you cancel and ship the order on the same day?
