I would contact them on Facebook

I really want recover my progress 
Honestly Facebook is your best bet, just keep poking them now and then. They’re usually pretty active.
Just wait a bit they will get back to you they are normally active between 3-7 for messages in the morning I’m in Australia
They are based in Tokyo and Seattle
