Mystery of missing baggage on flight QR 920 & very bad service

Mystery of missing baggage on flight QR 920 & very bad service I travelled from South Africa via Doha to Auckland New Zealand on the 8th August and arrived in Auckland on the 10th August. On arrival in Auckland I discovered that one of my suitcases had gone missing, I reported it to the Lost luggage tracking group(***), they are utterly useless and I struggle to get them on the phone or a response to me emails, musty have phone about 20 times and same number of emails. At time of writing I logged lost baggage claim with Qatar airways as well and wait for their feedback. Its now 5 days and nobody seems to know where my bag is, just imagine this ? in this day and age
