When you got off at LHR - wasn't someone from CX/BA waiting at the gate to help you transit faster? may be they knew you wouldn't make it and did not bother coming
Good luck with your compensation..No harm in trying

I think the OP is saying that the CX ICN-HKG flight was delayed hence they missed the BA HKG-LHR flight. They must have been rebooked onto one of the CX LHR flights (which sounds like it was pretty well dealt with to get them onto one of them - CX evening LHR flights leave only about 40 mins to 90 mins after the last BA one).
Then it sounds like the later CX flight arrival did not allow him enough time to make the connection at LHR and that's the issue, however, it started with the late arrival of ICN-HKG is what I'm hearing.
