Black horizontal lines on iPhone 13 display

When exposed to sunlight or when the temperature of the phone rises, black horizontal lines appear all over the display of my iPhone 13. I have visited the service centre 3 times regarding this issue but the service centre has not provided a proper solution for the problem. They asked me to submit the device and collect it afterwards. But they just reinstalled the software and return the device saying there is no issue in the phone. I am facing this issue within a week of purchase. This is a manufacturing defect and I want apple to replace my device.
