[does]

hi,
as u know when ordering miners from bitmain with a wiretransfer  bitmain allway get less than what u actualy sent.
lets say ur bank did a wiretransfer for 1k as required by bitmain, and bitmain gets 960$.
usualy u will get an email from Chita (Bitmain) saying u have to complete ur order by sending the rest of the money (40$) via wiretransfer or btc.

my question is, what happen if u dont pay the extra?
what happen to the money (my money)?
how long its taking to get the order canceled ?
i have heard u do  get credited ?? ( is that coupons?? how long does it take to get credited?)

(i have 2 orders which are meant to be sent in dec we are now in nov)

thanks alot in advanced .
