Just returned on a flight from CDG with CX and was treated, in my opinion, awfully by the CX check in staff who blamed me for the flight being over booked amongst other things. Anyway, I want to write to CX about it because I generally enjoy their service and was shocked to be treated and spoken to in this fashion when I was returning home for a family emergency and was stressed enough as it was. Anyone had any dealings with CX customer relations and are they responsive or would I just be wasting my time?
