Are you sure i can Send to them 284 000 K worth of bitcoins and its safe??

Who can I contact to make them cancel my orders, so that my stock which I ordered from previous orders (Once that bank didnt let through).
There is no more stock I think because my order has 3 day hold

Is anyone on these forums from Bitmain who can have a word with me ?
Its not 1 miner its about 160 Miners, which I though would be on a way soon..

Has anyone ordered by a wire transfer successfully before? Do you guys understand what Im talking about ? anyone has similar issuess?
