Asiana Airlines complaint: Delayed and damaged luggage

KMy husband and I travelled from Edinburgh yo Sydney, Business class via Frankfurt, Seoul , first 2 flights with Lufthansa and last one with Asiana. One of my checked bags did not arrive in Sydney, and remained untraceable by the airline for over 21 days. I repeatedly told Asiana that my bag was located in Frankfurt airport as I had an AirTag in the bag which located it there.
Eventually Asiana liaised with Lufthansa and the bag was forwarded to my daughter in Sydney,as I had travelled on to Tasmania by that time, but the handle of the bag is broken and therefore both the Airline tag and my own luggage tag were missing from the handle, hence the difficulty in identifying the bag.
My complaint is therefore:
1. Bag damaged by Lufthansa causing loss of identification labels.
2. Prolonged delay in connecting me with my bag.
3. Bag could not be delivered to me at my new holiday address, but instead had to be delivered to my daughter in Sydney.
4. Distress caused to me and my family: it contained several items that were Christmas presents for my daughter. Also my husbands golf shoes so has been unable to play golf. Also my own toiletries sone of which I have been unable to replace.
5. Poor communication from the airline; I heard nothing from Asiana after the first email on 2.1.25 acknowledging my missing bag, until 10 days later and after many emails from me. I found this lack of communication very frustrating and it has adversely affected the enjoyment of my holiday, and taken up a lot of my time.
