Lufthansa Beijing sucks!

After a great stay in Beijing, we left the Grand Hyatt right on time for the around 1 hours lasting journey to the airport by taxi.
Flight should have been a day flight leaving Beijing at 13.20pm and arrive @MUC in the evening same day. So we opted for LH Business Class, knowing well that there are better products in the air, but as premium costumers it shouldn't be a problem. Check in was a swift but security and passport control took ages as there is no priority lane. Still 30 minutes before flight we opted to check out the Air China Lounge which was more or less a nightmare as it was fu**ing hot at the airport. The Lounge offer free Internet access which is a plus. Just before heading to the gate I got told that there might be a minor delay. No problem so far, but I don't trust these guys and went to the gate to check. I asked Lufthansa staff at the gate about the delay and they said something about an hour and that we could go back to the Lounge again. i asked for the reason and they told me it is a "technical problem" with the aircraft. Well if you fly a lot you know, that technical issues won't be resolved within a couple of minutes. I went back to the Lounge to check my other option to reach my destination on that day and went back to the gate to request a rebooking to another flight or another night in Beijing. They refused and said that I will be fine as they intend to leave very soon. What a rubbish, got a text message right in this moment stating the flight will be delayed by another 4 hours! After long discussions with the flight manager, I got the OK from the immigration to leave China on another flight, which is not that easy, but besides there had been several more options he offered me to fly on my own cost to HKG and connecting on another LH flight to FRA. I refused as they should been in charge to make sure that I reach my destination on time. Later on I contacted the LH Station manager, a chinese Lady not willing to assist and lying to the costumers. She told me, that I am not allowed to leave the country on anther flight rather than the booked LH flight. That was the time I started to laugh even so it wasn't funny. I pointed out that I got the OK to leave already a few hours ago, she got really pissed off, why her flight manager was such a helpful person. End of the story- we left Beijing about 6 hours late, I missed my connecting flight in MUC and had to stay overnight. Did not got my luggage in MUC and had wear the same stuff again and again...
On top of that Lufthansa refuse to compensate us for the delay of around 14 hours and all the trouble caused!
Be aware as there is better way to fly!
