Does anyone know the authorized repair centers in Dubai for iPhones. Etisalat uses Technocare which are less than useless.

Question

I dropped by iPhone 4S two days after buying it, and would therefore like to get the damaged screen repaired at the authorized service center.
I took it to Etisalat (the carrier where I bought it) and explained clearly that I am aware that this kind of damage is not covered by warranty, and that I will pay for the repairs.
They took the device, two weeks later it was returned un-fixed with a message saying "Physical damage is not covered by warranty".
I resubmited the device, this time writing "Please quote for replacing the damage screen at my own expense. I am FULLY aware this is not covered by warranty".
Two weeks later...<drum-roll> the phone is back un-fixed with a message saying "Screen physically broken, not covered by warranty"
So if anyone reading this has any suggestion on where / how to get this phone repaired without voiding the warranty please let me know. Clearly the carrier (or their service center Technocare) are clueless.
Thanks.

Thanks Ingo2711,
The pages you suggested point to the local carriers as the only authorized service centers.
The problem with Etisalat is that they outsourced that service to another company called Technocare.
That company sent the phone back twice (for the reasons mentioned above) and suggested that I have it fixed at a third party, which I am refusing to do since that will void my warranty. Additionally, they are refusing to give me any thing in writing to that affect.
