I submitted a refund request for a batch 3 asic and have not heard anything yet nor received a refund.
Edit: This was about 6 days ago.
Since bitsyncom mentioned its possible i tried it yesterday too but without answer. Im pretty sure that yifu is reading each new ticket in hours because he answered fast to 2 of my tickets. Im not sure what it means to not get an answer on this. Maybe his statement that avalons are mass produced now means he will sit it out until the batch 3 are produced fast now?
But maybe he meant the production of avalon chips only.
Im wondering how it turns out. Will a refund be the full btc i paid or something like BFL-Style?
