He probably does have the money but involved in shady trading tactics, so his account was flagged.
You should contact them on twitter and see what they say.
Contacting them on twitter is no use they're going to say the same thing to him since OP already received a response from their support if you look at the reddit post linked by oeleo.
It's surely insane to keep 1200 BTC on an exchange, bad to post the same thing again & again and even worse to image edit the official e-mail by Binance (as Binance support team told at Reddit); however, the issue is starting to get "very old". IMO, Binance should've been able to resolve it by now, or at least they should constantly update him on the issue.
They shouldn't because he's already doing shady things like altering the replies. We all don't know the exact details of how it all started but who knows maybe he could be the scammer that's trying to claim the funds. If they speed up the process only because of these posts then Binance might give it to the wrong person plus he mentioned in the reddit thread that not all of the 1200 BTC belongs to him.
