I submit a complain ticket and I said I am not happy about the second batch shipping and the price drop. Then I said it is only fair if international buyer can also get a refund and reference this article.

Well let's see how they response.

Based on unconfirmed information from my friends in China on Wechat, they said a lot of people in China were very angry with Bitmain about the second batch of B3. They demand some kind of refund and not coupon otherwise further action / visits will be taken.

How true this is I really don't know but the least I can do is write a complain ticket and hope for the best.

They might ignore 100 complains but might act different if there are 500+.
