I have seen lot of people complaining about Wire Payment NOT being confirmed by Bitmain. Well, I am one of them.
Many users here claiming that there is a big banner about "Please make the payment ASAP so we can receive and verify it within 7 days. If we do not receive your payment within 7 days, your order may be cancelled".
Trust me. We know its critical and every one is eager to get their hands on miners. Everyone is excited about this. I have done the wire transfer next day I place my order. And now my order is "Unpaid, Unshipped, Expired" after 10 days. I have done similar wire transfer to other Asic Miner from same Exchange and my order was successful.
So why is Bitmain delaying in confirming the order? We are getting nervous about losing money here (even after paying on time).
