Emirates Airline - Shocking Customer Service

My son, Meerten van Wyk, booked his flight journey through Emirates via their online portal flying from Durban to Olbia in Sardinia via Dubai arriving lunchtime on Saturday 22 July. His bag went missing somewhere between Jhb and Olbia. It was properly reported at the airport. Emirates customer services simply referred us to Fly Dubai who was the last operator. We registered it on FlyDubai's website. The bag is now only scheduled to reach Olbia tomorrow and then has to be scheduled to be delivered. This is ridiculous to wait more than 3 days for your bag! When contacting FlyDubai to try to expedite neither the customer service or baggage departments was willing to assist saying that we needed to contact Olbia airport who was arranging the logistics with them. The baggage department's number at Olbia airport only has options in Italian we do not understand which is why we approached Emirates in the first place. Approached Emirates again for help which was again refused with a divert to FlyDubai. What shocking customer service! We booked through Emirates. Surely they can try to assist.
