Doesn't take much to post an update for everyone. Ignoring your customers is not a good way of business. Just makes them look stupid. I don't doubt the product, just their customer service.
Doesn't do much good. Take quite a while to to come back. And when they do, they don't answer your question and / or give you some generic reply like "soon" / "probably". They can't even give you an update specific to your order.
