it is a really big number, so how much did they earned in those 15 days ?
all i guess since they never ship the orders
But why people are still roaming around bitmain to order the antminer series hardware from them. Because of their delayment many investors are moving to ebay resellers to purchase the antminer s9 which is cost around 2k in the price of 3 or 4k US dollars.
You can contact to Bitmain support team to learn the issue and when this delivery will be recovered.
