Finally got through to them today. They said their email system was down and their phones were busy. For my trouble they are sending me 2 extra cases for free, besides a replacement for my current case.
They used to sell these cases for a penny and now they are $5, but they made money on the expensive per case shipping charge. True these cases don't last as long as $30 cases but Default will replace theirs for free anytime and are of a minimalistic design with decent coverage on the phone. If you drop your phone a lot I probably wouldn't use this case, but for normal every day use it makes for an inexpensive alternative. There is no protection on the top or bottom only the back and sides, with only a lip edge around the front. It doesn't add much thickness to your phone, which I like.
