First thing, let me made is clear, that what fear I described is a generalised one and no way related with Z.
Now to the point, yes they have to send margin statement, but only for the open positions, that is future positions holding at close of the day. While this type of herapheri is to be done when a trader closes his future trade and the blocked margin has to be released. I dont think if any trader has ever checked his blocked margin and then for released margin amount, after a trade, as it is no way feasible and possible to check it and so a herapheri of 100/200 will remain unnoticed
BTW, have you ever checked, that correct margin amount has been credited to your trading account, after squaring off a future trade
