Samsung — Samsung M51 Mother Board damage

Address:

Samsung India Electronics Pvt. Ltd. 20th to 24th Floor, Two Horizon Centre, Golf Course Road, Sector-43, DLF PH-V, Gurgaon, Haryana – 122202

I purchased Samsung M51 mobile from Amazon, but within 1 years 4 times mobile charging problems comes, I go every time Samsung service centers to resolve issue in every 2-3 month and every time problem coming, I think that problem was from factory but they did not understand that things and after repair provide me.

But according to me if problems come every time it's factory issue and company should replace it, but they did not do it.

Not last time it's problem again and I will go for service centers to repair it again but they told me it's screen damage and warranty finished.
Also told me your motherboard also damaged without any proof.

But how to problem within one year 4 - 5 times and also motherboard damage, screen damage etc.

According to company policy they are not ready to repair or replace it.
It's not fair with customer
