I've called CoinTerra customer support a few times now. First couple times I actually got a live human being on the phone. His name was John and was quite helpful in converting my Dec order into 2x Jan orders and refunding the difference back to me. A week later I called and left a VM. Surprisingly, I actually got a call back the same day!
I'm so used to getting terrible customer service from ASIC companies. It is quite refreshing to find good customer service for once! Of course I'll feel better once the miners get delivered, but good communication goes a long way in my book. Kudos to John from customer service!
