Question How can I unlock this thing!?

Guys I need help.

I bought a brand new Samsung Galaxy Note II on an Irish equivalant of Ebay (adverts.ie) knowing it was locked.
I thought maybe I could unlock it with one of those "unlock any phone now" websites. I tried two, returning the same
results. Failure. So how can I unlock it?

Any details needed just ask.

I'm in Ireland, phone is locked to Meteor network. It's the N7100, rooted with CWM and running Ditto's Note ROM (4.4.2)

Thanks in advance,

Chris.
