I can see where the OP is coming from, it seems that LH CS does not manage well cancellation for non status passenger (i.e. 90% of a plane). Only once LH cancel a flight on me 24 hours prior to scheduled departure and the handling by CS was very frustrating: no communication (I received the cancellation email 7 days after scheduled departure), refusing to rebook at a convenient time (they wanted me to stay 3 extra days at destination), then rebooking me on a partner (LOT) but asking me to pay the ticket, then scolding off as "OK we will rebook for free this time but we are doing you a favor. Next time a flight is cancel you will have to pay", 60 minutes on the phone ...
