If any of you know the rule authority’s for complaints regarding extra charge in hotels in abu dhabi? Please help me

If the managers are responding to emails and calls, regarding the pending refund one of the desk lady made from my account, what is the government I charge of this matter ? Unbelievable I paid twice for my room, and no one reply.

Dear Mr. Mourad Brahmi, this is Fab Morello and I hope this finds you well. I would like to submit to your attention my case, which refers to a double charge on my credit card, referred to my stay at Novotel Al Bustan ended last May 3. I talk about an amount in Euro currency not due, which now I have to pay to Amex, despite the information provided to them (e.g. Invoice received at the time of check out). Could you please look at my case and solicit your Finance team to refund the right amount to my AMEX credi card, as per what is indicated in your booking system and the invoice you provided to me at the time of my check-out? I'm a Gold member of your Accor Loyalty program and I didn't expect to find myself in such unpleasant situation. Thank you for your attention and consideration of my request. Best regards, Fab Morello.
