I plan to replace my Samsung note 9 battery. Checked out Samsung's repair service for 1 utama and their review was only 3.4

A few users complained that instead of having their phone repaired properly, it came back with even more problems. Any recommendations for other Samsung service outlet that is actually more reliable?

The reason I'm thinking of going back to their official service centre is because I would prefer them replacing with a genuine samsung battery instead of an OEM from China which may not have the necessary safety features. Thanks.
