So far the wife, who speaks chinease, has now spoken to china south today. took her hours to get to the right person. Now we are waiting on a call from them, will take place before this Friday.
After this I will start reporting them and dragging KLM in on everything

Don't settle for anything else than what they are due for you in Euros. I would also sent the person at China Southern a registered letter so that there is a document trail.
KLM sold you the ticket and was probably the ground handling agent, but the liability is with China Southern.
