Warranty Denial and Repair Cost Shock for iPhone 11 Water Damage

My iPhone 11, which was protected by a nearly indestructible screen protector and a case, fell into the sink. I quickly grabbed it, removed the case, and wiped it dry. Water did, however, get in through the SIM card slot. I immediately switched off the device and contacted Apple support to explain the problem. They informed me, much to my dismay, that it would not be covered by the warranty. I had previously been advised by a friend to visit an authorized dealer for repair and evaluation, so I did so. I explained the problem to the service center, only to be told they couldn't help me and, even more shocking, demanded a 19,500 tl repair fee, despite the fact that the device is only 5 months old. I can't go to the THH because the device is registered in the name of someone else. Please correct this error, or at the very least, repair my phone. When I had problems with the rear camera in the past, you were quick to replace my original screen with a fake one. You appear to be passing the buck now.
