I have had my problems resolved now.
I have managed to withdraw DUCK, FCN, BCN, QCN & MRO where I previously had trouble and my missing coins have been re-credited.
I don't believe there is any intention to scam as some people shout - but the performance and support has a lot of scope for improvement.
Needless to say I will be withdrawing my coins at very frequent intervals now.
I have been credited all missing coins and pending transactions from minergate - they did come through and sort everything out.
Thank you Minergate.

Guys, sorry for the issues, we really do our best to solve them and to improve the service.
It's not easy to be the first pool - first in CryptoNote (weeks ago), and then in merged mining. We're really getting close to flawless running.
Thanks for staying with us!
