Faulty Factory Windshield in my 2022 Opel Combo, Water Leaks Inside

2022 model Opel Combo Opel The windshield of my vehicle purchased from Erdemir Oto is faulty from the factory. I was kept waiting for many days. The vehicle was inspected and a water test was performed. Error detected. No one felt the need to contact me, I contacted the Opel center as a last resort and they stated that they gave their approval. No one returned. When I called the Opel center again, they stated that there is no record of this vehicle, they have no information about the customer consultant I met with and that this vehicle has no record file. We are afraid that the vehicle will have problems with the electrical components inside when it rains or when it is washed, if a product comes out of a defective factory, this product should be replaced by the company. While we are waiting for an apology, we cannot find a person from the huge Opel BRAND in front of us (Opel-Peugeot-Citroen is a regret.)
