Citroen C4X ECU Fault Under Warranty - No Spare Car

I own a Citroën C4X that is still under factory warranty and on 21 January 2026 the vehicle gave a brain/ECU fault. I took my car to the Uşak Citroën authorized service Çağdaş Otomotiv and was informed that a spare part had to be ordered from abroad and that the delivery time would be around 60 days. During this period, I requested a replacement vehicle so that I would not be left without a car, but the authorized service stated that they had no replacement vehicles and did not provide one. After this response, I tried to reach Citroën authorities in Turkey to convey my grievance and to find a solution, but I realized that it is almost impossible to reach any responsible person. There is no phone number or e-mail address for Citroën Turkey management that I can find. The only contact is Citroën Turkey customer service, and they only forward the issue back to the authorized service without producing any concrete solution. Since the service also does not solve the problem, the issue keeps going in circles between customer service and the service, and my vehicle continues to wait at the service. I am extremely dissatisfied with this unqualified and irresponsible after-sales service approach. I request that the necessary spare part for my vehicle be supplied as quickly as possible, the repair process be accelerated.
