Received my first correction today. Though it's not full it's around 10% ( .2 BTC) of what they owe me it's still a good sign.
As I mentioned in another thread I've waited for a long time to get an answer from the support so I guess we all should be a little more patient.
I got this Generic email today from them:
Dear User!

Thanks for your loyalty.
Best regards,
