Opel Frontera Spare Part Delayed Over 40 Days With No Clear Update

I am an Opel Frontera owner and I applied to Opel Nev Tarabya in Istanbul on 7 November for a spare part requirement for my vehicle with plate number 34NTL1**. I was informed that the relevant part was ordered on 9 November and would come from France. However, despite the fact that 40 days have passed since the order, the part has still not been shipped from abroad and my problem has not been resolved. During this period I contacted both Opel Nev Tarabya and customer representatives, but I was not given any clear date or definite information about when the part will arrive. All I was told is uncertainty, and I am left waiting without any planning or solution. I request the urgent supply of the spare part for my Opel Frontera, the completion of the repair process without any further delay, and the provision of clear and precise information about the status of the part and the process.
