I don’t think you will get much satisfaction with the Station Manager as they will protect their own people and then it may reflect poorly on them. BN is concentrating on telling you the price of tea in China, he will take a couple of weeks for that.
I think you have to find out who is in charge of the Station Manager, who is his/her Superior (preferably someone in Hong Kong). I don’t know the hierarchy of the Station Staff but someone has to bring this to their attention.
Someone in Flight Ops i.e. CP, DCP, Ops should know who to go to in this case.
