I have bought new samsung a7 hardly 7 months before and today when i woke up in morning there was color scattered on my screen but the touch screen was working fine.
When i reached out to customer care vashi branch near inorbit they directly told me it has been damaged and you will be charged rupees 7711. I tried to made them understand that physically everything is ok only its color problem on screen but they were ignoring me and just said u need to pay the amount.

I just dont understand that company claim of gorilla glass and other such hardware features and physically nothing is damaged only the amoled led screen is damaged due to which color is scattered on whole screen.

If such costly phones will be damaged so early how will consumer be satisfied.They have not even given proper mail id for complaint.
