Apple India — Facing same issue after repair

Hi Sir, " DEVICE SERIAL NUMBER: G6TY813PKPH1

" I have APPLE iPhone XS MAX and that is facing three issues

1- Heating, 2- Screen Freez 3- Camera Lagging Service Center

First Visit 16/06/2021 : THEY REPLACED DISPLAY but even after changing the device display my device is heating and freezing, So I resubmitted the device to the same service center and this time they told me that device is not showing any issue ( i shown this issue already to store manager Mr. Uppendra, Also recorded the issue in service center) but the service center is saying the device is fine.

1- if the device is fine then why they changed the display?
2- if they will be in the A.C Room then how they will check the device at room temperature? also, they are not checking the device properly. WARRANTY: My device in warranty, and they are wasting time because the warranty is going to expire soon.

VIDEO PROOF: I HAVE A VIDEO PROOF WHERE I RECORDED ISSUES IN THE SERVICE CENTER, HOME, OUTSIDE AS WELL.

IMAGE PROOF: UPLOADED, WHERE THEY MARKED DEVICE AS FIXED/DELIVERED BUT AFTER THAT ISSUE SHOWING ON SCREEN.

SOLUTION: my all work is based on iPhone and MacBook because I am an application developer. So Please replace this device as I can't visit the service center again and again.
