Etihad Airways review: Not giving customer rights to make a complaint

I called the custoemr servies and asked for if there is complimentory hotel for more than 22hrs transit, the lady said you need to spend $750 dollars on tickets and your ticket is $630 dollar so you are not eligible for complimentory hotel booking, After hearing this I asked her if she can let me know how to raise a complain as I am not happy about the policy and would like to raise a complain, she refused to provide me any email or directly me on how to make a complain but was insisting that I can provide a feedback only. Then I was persistant to ask if she can let me know if there is any form I can fill or email to complain as I beleive as a customer it is my right to do so, She asked me to be on hold while she can speak to her supervior, she came back with a same answer that I can only give the feedback, after hearing this I wasn't happy at all and asked for the supervisor name initially I got refused and she said she will speak to supervisor again and put me on hold, this time she came back and gave me information on how to make a complain but when I asked her the supervisor name she put me on hold again and went to ask the supervisor if she can give the name or not, so this time she gave me his name, Sahil. After that I tried to search complain form on the website on my own but coldnt find it so through internet I find this page to make a complain not sure if this will be heard. But I am planning to avoid travelling with Itehad any more where you have to show that you have spend certain amount to be eligible for complimentory hotel. I have never experience this while asking other airlines for complimentory hotel. Shamble experience will try and tell my family and friends too about my experience and to avoid the travel through Itehaad Airways feeling very disappoitment.
