You've misunderstood how things are going. Nobody confirm the transfer payid, an order before the money is actually in the Bitmain account.
Foreign transfer takes time. On a weekend, nothing moves with this transfer. It's likely that the money has not left your bank, or has arrived in a correspondent bank.
The bank is always unpredictable. Why did you pay for your order only on Friday afternoon? Love lotteries ?
You are always a loser here. Bitmain sells your miners to someone else . And if you are lucky, then in a few weeks you will get your money in the Bitmain account as a prepayment
