it's time to write a collective statement to the Chinese police)))  I already understand that we were deceived and stolen our money

no 

in a normal situation, they do not do that, there are clearly some problems. and how would they just do not close with our money

We were told a week ago by phone that your order will be shipped in mid-September. but now they say that we no longer produce them. I hope that everything will be OK with your order. but not sure.

now I need either my money back or A4 as promised and for what I paid. who will guarantee that they do not announce the A++ in December and will be asked to pay extra for it?

they do not offer, but put before the fact. A4 already finished and A4+ have not started yet.

they say that they no longer produce A4 !!!!! but how not to release if I have a pre-order for it ?? and not only for me but for a large number of people

they do not offer, but they say that this is the only way out and without a refund. is this normal for you? suppose you made a pre-order for A4 for the September, and they decided that you'd better buy an A4+ and wait another half a year. I myself want to decide what and when to buy for my money. there is an obvious fraud

WTF with Silicons?  

I preordered the A4 in July, for August-September delivery, now I am offered to pay extra and wait for December. its SCAM? How can this be? they risk the honest name of Charlie Lee, who praised them on his Twitter account.

I paid the money and waited two months to hear it?
