so, can i just sell all of my amber to this "AMBER company" (or should i call it imaginary "AMBER") and get back my 1.46 BTC ?

No that is not possible anymore as far as I can tell. It was possible untill March.
If so, that means that word of AmberTrade is worth nothing. Investment protection were officially promised and now it is cancelled? Where is investor's trust? It must be a misunderstanding.
