Opel Delays Repair for Months Due to Unavailable Mokka Spare Part

"When I took my Opel Frontera model vehicle to the Opel Nev Tarabya service on November 7th for fault detection, the authorized personnel broke the vehicle's screen during the inspection while checking the fault. Although this incident occurred entirely during their own inspection, the process has caused significant inconvenience for me. Because the screen is broken, the touchscreen does not work at all, so I cannot use any of the relevant systems in the vehicle, especially the navigation. Even though the car is under warranty, in my conversations with the service and customer service, I only receive the response 'we are waiting for the part,' and no clear solution or information is provided beyond this. Due to this error that occurred at the authorized service, I request that my grievance be resolved without further delay, that the broken screen be replaced under warranty, free of charge and quickly, and that I be regularly and clearly informed about the process."
