So, update:
Both batches were asked for refund. Waiting for John to receive the BTC back.
Steve, batch #1 has been already refunded. Please get in touch with JohnK for confirm and instruct him for processing refunds. Fact, that you don't know, that your own batch has been refunded is really funny.)
I confirm that I've received the refund for this specific group buy about yesterday night.

T13hydra, please confirm the list of users to be refunded with me and I'll try to process this ASAP.
