Reeder S19 Max Pro Screen Failed and They Returned Damaged with Missing Parts

My Reeder S19 Max Pro phone suddenly lost its screen display while in use. I sent it to the service center in Pendik Pendorya Shopping Mall, and the repair process took over 20 working days before the device was returned. During this time, I received a call informing me that my exact model wasn’t available and that I could upgrade to a higher model for ₺3600. I declined this offer, requesting that my device be repaired under warranty. Later, I was told that my device had “liquid damage” and was therefore out of warranty, with an option to replace it for ₺3600. However, my phone did not have liquid damage, so I found this claim unjustified. Upon visiting the Reeder store in Pendorya AVM, I noticed that my device had been returned with visible damage, an open case, and the SIM card slot missing—quite different from the condition in which I originally handed it over. The store manager, Mr. M***, agreed that this situation was unacceptable and assured me that he would escalate the issue to the regional manager to provide a replacement device. Despite this, I have had no response, and two weeks have passed with my phone still at the store, unusable and damaged. Since July 6, I have been left without my phone and feel significantly impacted by this issue. I kindly ask for your support in ensuring that necessary actions are taken.
