Translated, they can't ask for a refund because it's "completed".
Point #1: their customers can always refuse the shipment and get a complete refund.
Point #2: this means that HashFast has no will to cooperate, they won't help their first batch customers that will lose 75% of their investment.
Conclusion: They have given me the reason to move on on a legal battle. If you are an HashFast batch 1 customer, please join me. If you know a laywer with btc expertise in CA, please tell me.
