Mishandled Baggage

I arrived in Istanbul on the 28th April for a holiday. Today is the 2nd of May and I have been without my luggage since my arrival. After the airline spent several days trying to locate my luggage, I finally receieved a call on 1st May saying it had been located in Abu Dhabi and that I would be receiving it the next day. Right now I write because it is midnight 3rd May and I still have not received it despite being told that it had arrived. I have tweeted and called Etihad throughout and I feel the service has been disgusting. Despite some of the ground staff being helpful, I am STILL the one running around trying to find answers, they have not proactively been calling me with updates. This on top of the fact that the flights I caught were all late, without explanation, is why I will never fly with Etihad again and will advise anyone I come in to contact with about this shoddy airline.
