Dell India — problem with the charging of battery of the pc

Address:

Bangalore, Ahmedabad, Gujarat, 380015

I have purchased dell inspiron 15 7000 on 16th july 2019. Started using the pc on 9th april 2019 as i reside in hostel and the pc could be used when i returned to home.
In my family this is the second dell pc, as we were very satisfied with the first dell pc.
But unfortunately this pc is not up to the mark of my expectation, as the battery is not getting charged over 55%.
Till 55% the battery gets charged, and when it reaches till 55% the symbol shows "plug in not charging".
This much of the costly piece of a pc, delivering the technical mistake gave a mental shock to me as i never expected this kind of mistake in the company like dell.
I request you to resolve the issue at the earliest.
Replace the defective piece will be appreciated.
