Nokia India — nokia 5.1 plus battery damage

Dear team
I am really dissatisfied with nokia 5.1. Within 6 month it has developed charging issue. I came to nokia service center pefact solution point in nazafgar delhi. Got replaced motherboard. Within 2 month now the phone battery is bulging out. Service center is now refusing to accept this. They are clearly trying to avoid my case by giving false logic like server not working etc.
My bad that i purchased a nokia set and even had taken the guts to come to service centre which has usual bad service behaviour.
