Samsung — Samsung S9+ Water Test Failing and not able to be fixed by the service center

Hi Team,

Recently i had given my samsung s9+ phone for display and back panel change.
the display was changed on the same day and the back panel was changed after a week.
when the back panel was changed the mobile didnt get through the water test as the server was not able to detect the mobile( i had spent 3 hrs in the service center).
i had revisited the center on 18th Sep and handed over the device and till today the service center is not able to fix the issue and dont have any update on when it will it be fixed.
the Service center is Vasavi Telecommunications Samsung service center, yelahanka, bangalore.
