Baggage Damage

Flights were good but an item of baggage was found to have been damaged badly on arrival. The necessary forms were filled in and the bag was collected for repair. That was over a week ago and since then no response. Unable to make contact telephonically with any Emirates representative and the company that collected the bag are untraceable and the number on their collection receipt does not work. Impossible to get any progress on the matter. Disappointing for such a well marketed airline.
