My Honda Civic Keeps Experiencing Continual Paint Problems

After purchasing my Honda Civic brand new on 03.01.2019, I noticed paint peeling on the sides of the rear window a few years later. When I took my car to Honda Meroto service in Çorum, they said it was a factory defect that could be repaired under warranty. They stated that the rear window needed to be removed, repainted, and reinstalled. After this procedure, my car began to absorb water from the trunk a few months later. When I returned to the service, they suggested that the rear window was not properly sealed or that the drainage hose had come loose, and they promised to reseal the window and return the car. The same problem recurred. When I opened the car door last week after heavy rain, I discovered approximately 3-4 liters of water in the footwell of the left passenger seat. Not only was the window improperly sealed, but this time water had seeped into the space beneath the passenger seat from the trunk. On Thursday, I was able to remove the water with a carpet cleaning machine, but when I called the service, they said they were busy and could only accept my car by Monday. When we arrived, the attendant, S**** Hanım, was rude and indifferent, stating that my car's rear window would be removed for the third time. When I complained for the third time, I wondered, "Is this going to happen every time?" I received the following response: "If it doesn't work, we'll do it again; after all, it's covered by warranty." "People get sick from this." When I threatened to file a complaint, they said, "Feel free to start legal proceedings; it won't affect us." They stated that they were unable to remove the parts in the passenger area and could not put in the necessary effort. When I contacted headquarters, they promised to call me back, but my car has been in service for five days and I have received no response. I am experiencing financial and emotional harm.
