Cupra Service Online Booking System Errors Prevent Routine Vehicle Maintenance

For about a month, I have been trying to schedule a maintenance appointment for my Cupra Formentor at the Eskişehir Asil Otomotiv service center, but I am continuously denied an appointment due to full booking. During my online attempts, I receive a "no available dates found" warning from the system and cannot select a date for maintenance.

I want my vehicle's regular maintenance to be performed on time, but being unable to get an appointment from the authorized service center for such a long period is causing significant hardship. I demand that Eskişehir Asil Otomotiv schedule a suitable maintenance appointment for me as soon as possible and provide a permanent solution to this scheduling problem.
